Tesla’s Push to Build a Self-Driving Car Sparks Dissent Among Its Engineers

Neither the driver nor the car manufacturer will have clear responsibility when there is an accident. The driver will blame the system for failing and the manufacturer will blame the driver for not paying sufficient attention. It's lose-lose for everyone. The company, the drivers, the insurance companies, and other people on the road.
Everybody who's looked at this seriously agrees. The aviation industry has looked hard at that issue for a long time. Watch "Children of the Magenta".[1] This is a chief pilot of American Airlines talking to pilots about automation dependency in 1997. Watch this if you have anything to do with a safety-related system.
It seems that we are locked into a spiral in which poor human performance begets automation, which worsens human performance, which begets increasing automation. The pattern is common to our time but is acute in aviation. Air France 447 was a case in point. - William Langewiesche, 'The Human Factor: Should Airplanes be Flying Themselves?', Vanity Fair, October 2014
Eventually mean/median system performance deteriorates as more and more pure slack and redundancy needs to be built in at all levels to make up for the irreversibly fragile nature of the system. The business cycle is an oscillation between efficient fragility and robust inefficiency. Over the course of successive cycles, both poles of this oscillation get worse which leads to median/mean system performance falling rapidly at the same time that the tails deteriorate due to the increased illegibility of the automated system to the human operator. - Ashwin Parameswaran (2012)

You are correct in the ratio (1:100) but I think you mistook departures for flights and extrapolated 2 orders of magnitude too far.
You sure about that number? Seems incredibly high to me.
This isn't just a matter for Tesla. The auto industry is rapidly heading for much better assistive driving systems. There's no way that the people heads-down in their cell phones are going to do this less once they realize they don't really need to pay attention.
Will accident rates get better overall anyway? Who knows? But systems that aren't intended for autonomous use are going to get used that way.
I loved this system and have always wished for something like this on a car in the US. I've never liked the common cruise control in the US -- where you set a target and it applies the gas for you -- because I didn't like how removing my foot from the gas pedal moved my foot fractions of a second further from the brake in an emergency.
It's not even just that, it's worse at managing the use of the gas overall than a human with regards to cars as of 2015, it seems like the system is worse at managing the gas than humans are. I'm not a huge fan of cruise control as defined above because I find it makes me really inattentive (my problem, of course), but the benefit of not using the cruise control is that it seems like you get much better mileage. My family used to have to drive regularly between Minnesota, Wisconsin, and Illinois for a few years, and I would always get better mileage not using cruise control than my brothers (who used cruise control) would. The difference would often be as much as half a tank of gas or more on older cars (2000-2010) and on relatively newer cars (2015) it'd still be a difference of a fair number of gallons.
I think the systems just aren't good at predicting when to coast and when to accelerate, and for very hilly regions, this means a lot of wasted gas.
This way my foot can readily cover the break pedal and I initiate breaking much quicker than off-gas>on-break
I view cruise control as a safety feature. I can keep my foot hovering over the brake pedal instead of on the accelerator, reducing reaction time in a crisis. Maintaining attention on the road has never been a problem for me, though I suppose the hovering-foot posture helps.
One catch there is that it'll stop automatically, but it won't ever go if it came to a full stop - you need to tap the gas to reactivate cruise. If the car in front of you starts moving, but you don't move, it'll make a noise (both audio, and visual on the dashboard) to remind you that you're supposed to do that. I suppose that's a kind of a safeguard to keep the human alert?
The lane tracking isn't that great, but I don't mind it that much. I don't use it much for normal driving, but I found it it's pretty fantastic in heavy crosswinds. The car does a pretty good job of keeping the lanes (assuming you can see them well enough) so you basically drive like normal instead of having to constantly fight wind gusts.
Under normal conditions it doesn't do enough to be terribly useful and less you're not paying enough attention… at which point you shouldn't be using it anyway.
Cruise control seems fairly harmless - you still have to keep lanes, and keeping your foot on the gas isn't particularly demanding either. I largely use cruise control because I am able to save on gas that way, by avoiding unnecessary acceleration/deceleration. Combination with lane following and holding of distance is more problematic imo.
The counter-argument is that they do this without Autopilot anyway. Given that they're already not paying attention, adding in Autopilot seems like a net gain.
https://www.autobytel.com/car-buying-guides/features/10-cars...
Also, as a pilot, I can tell you that the Tesla Autopilot functions very much like what we have in planes. It steers the vehicle and significantly decreases workload while increasing overall safety but needs to be constantly monitored and can easily be misconfigured or operate in unexpected ways.
Remind me not to drive in your neighborhood. (This appears to be hyperbole.)
People rear-end each other in my city every day. On my commute, I'll come across two a day. Wet days, a few more. The other five directions headed into the city I would expect to see similar statistics to my experience. Just listening to traffic radio, there's going to be at least five crashes around the city; almost always more. They don't report on fender benders.
I don't think I ever saw three separate rear-ends in a single drive. I can't say for certain that I ever saw two. I didn't drive it every day, but I probably did 100 such commutes.
You sound either like you're massively exaggerating or live someplace with apocalyptic traffic.
Whenever you get full speed traffic occasionally interrupted by traffic jams (from whatever cause, other accident, tolls, weather, low angle sunlight, construction, etc.), you'll get a higher incidence of rear-enders. Especially when the tail of the slow/stopped traffic is at a point just past a hill or curve.
I got rear-ended myself some years ago in just such a situation, clear sky & dry road. The traffic ahead had slowed dramatically driving into a section where the bright, low winter sun was in everyone's eyes, we couldn't see that before the gentle bend & rise in the road, I saw the slowing traffic & had to brake hard, the person behind me braked late and hit me even though I'd tried to stretch my braking as much as possible to give her more room. There was another similar accident minutes later just behind us.
This kind of rapid-slowing situation in tight-fast traffic will likely even get out of hand even for automated cars, unless there is car-to-car communication. This is because of the slight delay for each successive slowing car in the accordion-effect accumulates to the point where eventually the required reaction time decreases and required deceleration rate increases past the performance envelope. At that point, a crash is inevitable.
With car-to-car communication and automation, the last car in the pack can start braking almost simultaneously with the first one and avoid this.
So, no, it's not hyperbole, it's ordinary.
Is this really true?
It seems like, as long as the following delay between cars is greater than that reaction delay, there should be no such "accordion effect."
2 is average for about a 60 mile drive during slightly off-rush. I suspect rush is higher.
And certain areas just seem to attract idiots.
What are you measuring? The current autopilot already appears to be materially safer, in certain circumstances, than human drivers [1]. It seems probable Level 2 systems will be better still.
A refrain I hear, and used to believe, is that machine accidents will cause public uproar in a way human-mediated accidents don't. Yet Tesla's autopilot accidents have produced no such reaction. Perhaps assumptions around public perceptions of technology need revisiting.
> Neither the driver nor the car manufacturer will have clear responsibility when there is an accident
This is not how courts work. The specific circumstances will be considered. Given the novelty of the situation, courts and prosecutors will likely pay extra attention to every detail.
[1] https://www.bloomberg.com/news/articles/2017-01-19/tesla-s-a...
Pilots and conductors are trained professionals. The bar is lower for the drunk-driving, Facebooking and texting masses.
> Systems that do stuff automatically most of the time and only require human input occasionally are riskier than systems that require continuous human attention, even if the automated portion is better on average than a human would be
This does not appear to be bearing out in the data [1].
[1] https://www.bloomberg.com/news/articles/2017-01-19/tesla-s-a...
The concern is that as level 2 autopilot gets better and disengagements go down, the human's attentiveness will degrade, making the remaining disengagement scenarios more dangerous.
Actually the study explicitly doesn't show that.
First of all, in the study, it purely measures accident rate before and after installation, so miles driven by humans are in both buckets. Second of all the study is actually comparing Tesla before and after the installation of Auotsteer and prior to the installation of Autosteer, Traffic Aware Cruise Control was already present. According to the actual report:
The Tesla Autopilot system is a Level 1 automated system when operated with TACC enabled and a Level 2 system when Autosteer is also activated.
So what this report is actually showing is that Level 2 enabled car is safer than a Level 1 enabled car. Extrapolating that to actual miles driven with level 2 versus level 1 is beyond the scope of the study and comparing level 1 or level 2 to human drivers is certainly beyond the scope of the study.
You are correct. We do not have definitive data that the technology is safe. That said, we have preliminary data that hints it's safer and nothing similar to hint it's less safe.
Safer than? Human driving? No, we don't.
As far as I know it is indeed correct that autopilot safety is statistically higher than manual driving safety (albeit with a small sample size).
However, something has always bothered me about that comparison ...
Is it fair to compare a manually driven accidental death (like ice, or wildlife collision) with an autopilot death that involves a trivial driving scenario that any human would have no trouble with ?
I don't know the answer - I'm torn.
Somehow those seem like apples and oranges, though ... as if dying in a mundane (but computer-confusing) situation is somehow inexcusable in a way that an "actual accident" is not.
[1] https://www.tesla.com/blog/upgrading-autopilot-seeing-world-...
That's a good question. Clearly, existing self-driving tech is safer than human drivers on average. However, "average" human driving includes texting while driving, drunk driving, falling asleep at the wheel, etc. Is the appropriate comparison the "average" driver, or a driver who is alert and paying attention?
The most appropriate comparison set would be the drivers who will replace themselves with autopilot-steered vehicles.
Have there been any Tesla autopilot fatalities with the right conditions to spark outrage? That's a sincere question as maybe I've missed some which would prove your point.
The only major incident I'm aware of is one in which only the driver of the car was killed. In an accident like that it is easy to handwave it away pretty much independent of any specifics (autopilot or no).
A real test of public reaction would involve fatalities to third parties, particularly if the "driver" of the automated vehicle survived the crash.
The actual performance of these machines will be the ultimate test. If it does consistently improve safety then I don't really see much barriers existing here, the current unknowns and semantics surrounding it will be worked out in markets and in courts over an extended period of time and will ultimately be (primarily) driven by rationality in the long run.
The safest option will be the way the market will be incentivised, despite all the noise around it this is the ultimate rational market.
Insurance is so boring it is interesting to me.
It depends on how you measure this. We always talk about humans being bad at driving. Humans are actually amazingly good drivers conditioned upon being alert, awake, and sober. Unfortunately a good fraction of people are in fact not alert. If you don't condition on this, than yes, humans suck.
(Put another way, the culture we, including companies such as Tesla, foster of working people overtime is probably more responsible for car accident deaths than anything else.)
The FAA takes pilot rest time seriously. Considering car accident deaths exceed airplane deaths by a few orders of magnitude, it's about time the rest of the world take rest equally seriously as well.
Comparing autopilot Tesla fatalities versus average fatality rate on one road section is dishonest.
>According to Tesla there is a fatality every 94 million miles (150 million km) among all type of vehicles in the U.S.
>By November 2016, Autopilot had operated actively on hardware version 1 vehicles for 300 million miles (500 million km) and 1.3 billion miles (2 billion km) in shadow mode.
Those numbers are 9 months old and only apply to Autopilot v1 and not the Autopilot v2+ introduced late last year. I wouldn't be surprised if the current number is in the 500+ million mile range with only a single fatality. The sample size is obviously small, but there seems to be a clear improvement over manual control.
[1] - https://en.wikipedia.org/wiki/Tesla_Autopilot
EDIT: With chc's and my post we have 3 numbers and dates for reported Autopilot miles. Projecting that forward at a linear rate (which is conservative given Tesla's growth) would put us at roughly 750 million miles today.
What I wonder when I see these statistics, though, is whether all miles are really equal? For example, are Tesla drivers more comfortable using Autopilot in "easy" driving situations? Is there really a one-to-one correspondence in the distribution of the kinds of miles driven with Autopilot on vs. normal cars?
Furthermore, the metric commonly cited is "fatalities ever N miles." Are there fewer fatalities because Autopilot is great, or because Teslas are safer in general? Has there been a comparison between fatalities with/without Autopilot strictly on Teslas? Even then, it seems to me we are subject to this potentially biased notion of "miles" I mentioned previously. The Wikipedia article you mentioned cites a 50% reduction in accidents with Autopilot, but the citation is to an Elon Musk interview. I haven't yet seen anything official to back this up, but if anyone has any information on this, I'd love to see it!

That's got to open up some liability questions. You can bet when people die it will be tested in court. You could make a case that Tesla's going to be liable for many level 2 accidents in the long run anyway, so might as well go all in ASAP.
I think cameras will hit parity with the human eye, but the question is will it happen before or after Lidar becomes more affordable and compact.
I've probably gone about 8,000 miles on autopilot in mine (AP1) and it is truly amazing. After a road trip stint of ~200 miles, I feel much more energized and less fatigued in the Tesla with autopilot 99% of the way than I do in previous non-autopilot cars. It really is a game changer. You may think regular driving doesn't require much brain activity, or that the Tesla cruise control and auto steering don't do much, but you really don't realize how much your brain is working to handle those things until you can take a step back and let the care do most of the work. Then you can focus on other things while on the road that you didn't realize before. The behavior of other drivers for example. I can watch a car near me with greater focus and see what that person is doing.
Regardless, if you have not driven one, I highly encourage it. You really need to take it out on the highway and drive it for 30 miles+ to really understand how amazing it is. I've driven other cars with "autopilot", and just like car reviews say, they are nowhere close. (Mercedes, Cadillac, Volvo, others with just auto cruise control). It's just one more reason why current Tesla owners are so fanatic about their car, there is nothing else like it and most likely won't be until ~2020 (maybe).
Would you say the same after if you happen to get involved in a serious autopilot accident though? That's the question.
It's very easy to be all roses before one sees any issues.
For instance, the one single fatality of autopilot to date in a Tesla, where the guy was coming up to a crest of a hill with a white 18 wheeler crossing perpendicular to the highway. Yes, the autopilot misread the 18-wheeler to be a sign above the road. (This issue is not fixed). However at the same time, the guy completely disregarded Tesla's instructions of keeping your eyes on the road at all times. Turns out, he was watching a show on his phone.
But yes, I would still say the same thing if I was using autopilot properly as intended. i.e., not watching movies while in the drivers seat of a moving car (which is against the law regardless.) I don't think there are any serious accidents to date where the driver was using it properly and following the rules. As Tesla states, autopilot is in beta (and most likely always will be), that's not to say it is unsafe, but that the driver must be aware and follow the rules and know what autopilot is and is not capable of.
I'd say it took me about two weeks of first using autopilot to understand its capabilities.
Also the best part, it keeps improving in my vehicle through updates. It's pretty impressive how good the updates from Tesla are.
I've never seen autopilot disengage by itself. It will after 3 warnings to the drive where they don't touch the wheel, I've never done that though.
There was one time, not quite an emergency, but basically my contact fell out of my eye, into my lap somewhere, and because I had autopilot on, it allowed me to safely use a few extra seconds needed to look down to find it. Whereas without autopilot, the number of seconds it took to find it normally would be considered very dangerous to look away from the road that long.
I believe Auto transmission (AT) car drivers are more easily distracted than those driving stick shift or manual transmission (MT)).
But AT makes life easy for so many people, that no one even considers if AT is making drivers less attentive.
A classic example of this, the worst case scenario I have seen in person, is that of a woman talking on a mobile phone in one hand while switching lanes and taking a left turn at a traffic signal. Things like this just wouldn't be possible if that woman was driving a stick shift.
In that driver's case, probably a Tesla like Level 3-5 driving system would be ideal, making it much safer for drivers around.
So, should we go back to MT for everyone or nothing? Just to be under the impression that it's much safer? Or should every vehicle be a level 3 to level 5 autonomous vehicle?
I think people choosing any of the above options will have valid points and research to prove their points. Only time will tell when and how any of those research results continue to hold true.
FWIW, in the UK where manual is more or less the norm, using a phone whilst driving is still fairly common (the penalties were increased recently due to people ignoring the law). From what I've seen, a lot of people will use the gear stick with the phone in the same hand (i.e. brief break in conversation whilst they switch gear).
i heard that this is why autobahns are made with unnecessary curves/turns.
This approach worked well (for some parties) in many other areas, for example in education: now the teachers are the only ones left responsible for the structuraly failing education system.
Now, if these were 1930s, with hundreds of independent auto makers, perhaps the invisible hand of the market would fix this.
https://www.bloomberg.com/news/articles/2017-01-19/tesla-s-a...
I don't see how you can get to L5 without L2 and the learning that is going on in these cars today.
You can use the automation as a backup safety feature until it's L4. For example, the car has the ability to stop if you try running a red light, but you otherwise are required to drive the vehicle.
Automated cars don't just have to be better than humans, they have to be as good as humans with automated safety features.
So there is always something to do.
This isn't building a bridge. If a company builds a bridge and it collapses and kills people and it turns out they didn't hire qualified structural engineers or that the CEO ignored warning from the engineers to push the project for a scheduled release window or to keep profits high - the CEO goes to prison for criminal negligence. With self-driving cars, it's a different story COMPLETELY. You're talking about SOFTWARE. No company that's killed people with software has ever found themselves being found guilty of criminal negligence. And they won't for the forseeable future.
This is how self-driving cars will go. I'll give you whatever you want if I'm wrong. I'm that confident. A company, using standard modern business practices (that means doing absolutely every single thing research has shown destroys productivity and ensures the end product will be as unreliable, and poorly engineered as possible. Open floor plan offices, physical colocation of workers, deadlines enforced based on business goals rather than engineering goals, business school graduates being able to override technical folks, objective evidence made subservient to whoever in the room is more extroverted, aggressive, or loud, etc. You know, you probably work in exactly the kind of company I'm talking about because it's almost every company in existence. Following practices optimized over a century to perform optimally - at assembly-line manufacturing processes. And absolutely antithetical to every single aspect of mental work.) will rush to be first to market. Maybe they'll sell a lot, maybe not. That's hard to call. What's NOT hard to call is the inevitable result. Someone dies. Doesn't matter if its unavoidable or not. No technology is perfect. That doesn't matter either. Won't matter what "disclaimers" the company tries to pull trying to say it's in the drivers hands. The courts won't care about that either.
But... they will absolutely get away with it. They will not be fined, they will not be forced to change their practices (most likely they will not even be made to REVEAL their development practices at all). You see, if the courts bother to ask what their practices are, their lawyers will point out it doesn't matter. There's no such thing as "industry standard practices" that you could even CLAIM they failed to follow. So their software had bugs. As far as the court is concerned, that's a fact of life, it's unavoidable, and no company can be held responsible for software bugs. Not even if they kill people.
So they'll get away with it - in the courts. In the court of public opinion? Nope. You see, even if they made their self-driving cars out of angel bones and captured alien predictive technology and it never so much as disturbed someones hairdo, they are destined to fail as far as the public is concerned. Because human beings are, shocker, human beings. They have human brains. Human brains have a flaw that we've known about for ages. Well, by "we", I mean psychologists and anyone whose ever cared enough to learn Psych 101 basics about the brain. There is an extremely strong connection between how in-control a person feels they are and how safe they feel they are. Also, feeling safe is stupendously important to humans. This is why people are afraid of flying. If things go wrong, there's nothing they can do. (The same is true when they're driving a car, but people are also often just wrong and they wrongly think they have some control over whether they have a car accident or not. No evidence suggests they have the ability to avoid most accidents.) If the self-driving car goes wrong while they're not paying attention, nothing they can do. People will be afraid of them as they are of flying.
And if you haven't noticed, our society deals poorly with fear. They LOVE it way too much. They obsess over it. They spend almost every waking hour talking about it and patting themselves on the back about what they're doing or going to do to fix their fears and the fears that threaten others. Mostly imagined fears, of course, because we're absurdly safe nowadays. So it will be the only thing talked about until unattended driving laws get a tiny extension to cover the manufacturing of any device which claims to make unattended driving safe. It'll pass with maybe 1 or 2 nay votes by reps paid for by Uber, but that's it.
This is a great analogy, because at the dawn of flight, many people were really, really really afraid of flying -- for very good reasons: the airplanes of the day were incredibly dangerous.
Yet people still flew, and flew more and more, despite many very public disasters in which hundreds of people died, and the airline industry grew and flourished.
Now most people don't think twice about flying, as long as they can get a ticket they can afford. Sure, some people are still afraid of flying, but most of even them fly anyway if they have to, and the majority aren't afraid at all or don't think about it.
When a mom is saying 'I'm not putting my children in one of those killmobiles' and someone says 'well actually ma'am its much safer and you're endangering your childs life significantly by taking the wheel', that person gets punched in the face and lambasted on social media as an insensitive creep. That's just how it goes.
Are you sure? What about IEC 61508 and ISO 26262? The latter especially, as it was derived as a vehicle-specific version of the IEC standard.
It's an industry-wide standard:
https://en.wikipedia.org/wiki/ISO_26262
...geared specifically to ensuring the safety of electrical, electronic, and software of vehicles.
Look it up - you'll find tons of stuff about it on the internet (unfortunately, you pay out the * for the actual spec, if you want to purchase it from ISO - it's the only way to get a copy, despite the power of the internet, afaict).
...and that's just one particular spec; there are tons of others covering all aspects of the automobile manufacturing spectrum to attempt to ensure safe and reliable vehicles.
Are they perfect? No. Will the prevent problems? No.
But to say there isn't any standards to look to isn't true.
Mostly, the drivers, insurance, companies and other people on the road have fewer accidents.
My point is, that all of this affects the public perception of self-driving cars - and if we want them to succeed, we need to make absolutely sure that that perception is good. We can't have the nonsense Tesla is trying to pull off at the moment, where they call their system "autopilot" but they know the system cannot detect obstacles at around pillar-height and it gets blinded by the sun and can swerve into the oncoming lane before just switching off. These are not theoretical problems - both happen in cars that are out there, right now. And if it happens to a regular Joe Smith, then Mr. Smith will think the technology is crap, and we can't let that happen.
We make these exact choices all the time. I am saying we should "let more people die" now, so that we can save more later. That's not a novel concept.
Ideally, we should embrace them even if they are slightly more dangerous than human drivers, because we are getting the benefit of the time that would otherwise be spent driving.
I've been saying for years that the right approach was to take the technology from Advanced Scientific Concepts' flash LIDAR and get the cost down. I first saw that demonstrated in 2004 on an optical bench in Santa Monica. It became an expensive product, mostly sold to DoD. It's expensive because the units require exotic InGaAs custom silicon and aren't made in quantity. Space-X uses one of their LIDAR units to dock the Dragon spacecraft with the space station.
Last year, Continental, the big century-old German auto parts maker, bought the technology from Advanced Scientific Concepts and started getting the cost down.[1] Volume production in 2020. Interim LIDAR products are already shipping in volume. Continental is quietly making all the parts needed for self-driving. LIDAR. Radar. Computers. Actuators. Cameras. Software for sensor integration into an "environment model". They design and make all the parts needed, and provide some of the system integration.
Apple and Google were trying to avoid becoming mere low-margin Tier I auto parts suppliers. Continental, though, is quite successful as a Tier I auto parts supplier. Revenue of €40 billion in 2016. Earnings about €2.8 billion. Dividend of €850 million. They can make money on low-margin parts.
Continental may end up quietly ruling automatic driving.
[1] https://www.continental-automotive.com/en-gl/Passenger-Cars/...
I suspect that if/when LIDAR is cheap enough, Tesla will use it.
In the meantime they outfit every single car with the best hardware that is realistic from a cost standpoint today, instead of waiting til 2020.
And so far, it just sits there and does nothing useful, since the self-driving software that can do the job safely with those sensors doesn't exist.
Musk's argument is that we know for certain that the
entire road system can be navigated by visual cues
We know for certain that human brains can be assembled out of regular atoms, but raising funds for a company that manufactures brains would be getting rather ahead of our current level of technology. The same might be true of computer vision and autonomous vehicles. It messes with formatting on both mobile

Oh?People and machines behave and understand the world differently. Just because it works for people doesn't mean it'll work for computers.
A vast amount of data has produced every driver.
Now if you want to just look "total experience in the world as a whole" the numbers look a bit different, but if anything that just accentuates the differences here. We don't currently have a way to teach computers to construct mental models of how the world works the same way humans think about it, which would be necessary to use training data that was about the world as a whole.
I agree fundamentally though that it's a weak argument to say a certain approach should be taken just because it's how humans do it.
i'm hesitant to argue against Musk, yet the actual goal is to navigate better than humans, and it seems reasonable to suspect that having wider range sensors would be a good (and may be necessary) foundation to achieve it.
Without good hardware then you're stuck jumping through hoops to do all the processing software-side which leaves less time to react quickly and accurately.
I worked on a team that evaluated the ASC unit a few years ago, but they found it unusable due to bloom issues. Has that changed?
Flash LIDAR has a tradeoff between range and field of view. You can concentrate your energy or fan it out. There's been some interest in systems where you can narrow the output beam when you need to. Or you can combine wide-beam short-range units with narrow-beam long range ones.
There are other flash LIDAR companies, but many of them are vaporware. Quanergy, which bills itself as "the leading provider of solid state LIDAR sensors" announced a unit last year, but doesn't seem to have shipped. Velodyne wants to come out with a solid state product. TetraView is trying for a low-end semiconductor solution that uses common sensors. Luminar and LeddarTech want to use MEMS mirrors.
A long-range narrow-beam MEMS-steerable flash LIDAR might be useful. Look out 300m in the direction you're going when at high speed, and use other wide-angle sensors for a side view and in cluttered city environments.
Somebody is going to get this working at an acceptable price point reasonably soon.

I think I agree with this, but is LIDAR expected to work in the rain?
Instead ask: "In good weather, can LIDAR-less systems match the safety of LIDAR?" The answer is "not yet"
Until LIDAR-less systems can match the safety of LIDAR they will simply be banned from the roads, or limited to certain situations such as rainy weather.
Regulators, politicians and society will not allow Tesla to operate a system which in good weather has a much higher accident rate than is necessary - and they will not accept "cost reasons" as a valid excuse for not installing a LIDAR.
Laws are frequently named after a single child who died.

And Tesla's engineers aren't the first to bellyache about being asked to make the impossible a reality.
I don't think the majority understands what safety means in mass transportation. It's not about running miles and miles without accidents and basically saying "see"? It's about demonstrating /by design/ that the /complete/ system over its /complete/ lifetime will not kill anyone. In terms of probability of failure it translates in demonstrated hazard rates of less than 1E-9 /including the control systems/. This take very special techniques and if that could've been done using only vehicle sensors, it would have been adopted by us long ago. I am also sorry to report that doubling cameras and sensor fusion will not get you an acceptable safety level. We've tried that too, rookies.
Is it "fair", to use Elon's argument? After all, isn't additional safety enough compared to existing situation. Ah but we have been there too! For driver assistance it is indeed better. Similar systems were deployed during the second half of 20th century (e.g. KVB, ASFA, etc). But the limit is clear. It only /improves/ driver's failure rate. It does not substitute for the driver. If you substitute, you have to do much much much better. Nobody will ride a driverless vehicle provided the explanation that it is, you know, "already an improvement when compared to a typical driver". Is it fair? Maybe not, but that's the whole point for entrusting lives to a machine.
In other words, it is you that is taking your own opinion for the universal truth. You reason in a model where the driver is the only responsible party for reckless driving.
An even bigger driving factor (pun intended) will be that the cost of a driver relative to operation is much, much higher in a car. A solution that is better on both safety and cost will be quickly adopted.
It does not matter how well your car can brake. Can your autonomous driving system guarantee it will always brake as hard and as fast as required when you will need it? Can you guarantee that the system will not have a bug the day it needs to brake?
Trains brake very well. There are even rubber wheel metros that brake so well we have to limit them in order not to sent everyone flying in the wagons :).
But in the safety calculations, standards like IEEE 1474 assumes degraded braking capability, and also considers that the preceding train is at stop. In other words, to be declared safe for mass usage, you can't assume average case. You must assume adverse case. You will not have a driver to notice that the car brakes poorly or to be confident enough to drive very close to the preceding car.
For the second paragraph, again, this is certainly true for driving assistance, but will most likely not be enough for driverless, as it was / is not enough for trains. Of course you may disagree.
EDIT: this is a good reference: https://www.linkedin.com/pulse/safe-braking-model-explained-...
However I don't see how the fears of an industry that needed to have extremely good results immediately need to be extended to one in which all signs point to progressive improvement. The danger being that the general public is fast to jump on blind trust, but to be compared with a vastly different ratio of number of people who are / can be in control to number of people affected, at least for cars and trucks which as far as I know are the first POIs in this industry. Autobuses might get automation slower than the rest of the fleet (no source, just from the top of my head).
First, you do not need self driving car to achieve 5x improvement. Good driver assistance systems will get you there.
Then, put yourself in the choose of the politician that is authorizing this technology to be used massively. Picture the amount of cars that are going to run everywhere once this authorization is given and ask yourself: what will happen to him once the first hundred people have died because of a wrong autopilot decision (it will be such figures, since you are OK with x5 reduction). Do you think he will be sleeping well at night? Do you think his political career will be better, especially if you consider my first point? Would you step in his shoes?
> You are willing to take the risk, but society as a whole will not.
What are you talking about? People very objectively ride planes that are not completely safe. Airlines that are nowhere near completely safe still get tons of customers.
EDIT: theses standards are applied worldwide, despite the EN prefix.

> Nobody will ride a driverless vehicle provided the explanation that it is, you know, "already an improvement when compared to a typical driver".
I don't necessarily think this is true (perhaps age-correlated?). Let's set aside the issue of whether or not we can do it, for now, and assume that we have a scenario where self-driving cars are safer than human drivers.
In this context, I can easily imagine a political campaign à la "Think of the children!" that paints human drivers as fundamentally unsafe, advocating for a self-driving mandate in urban areas. Perhaps with a Cash-for-Clunkers type of deal to aid the transition. I am not saying this is desirable, merely plausible; it has all the elements of good politics: an easily-grasped bright-line dichotomy, emotional manipulation, and massive corporate benefits (for vehicle manufacturers, self-driving software vendors, and transportation providers like Uber).
For the second part of your argument, there are multiple problems, again backed by examples in the railway world.
First, a politician will think twice before casting a devilish image of drivers. Having all the professional drivers against you is essentially a political hara-kiri. There is a reason why it took 10 years to migrate Paris Line 1 to driverless, and it is not technology.
Second, you would not believe how difficult it is to reach consensus on the fact that drivers are unsafe compared to a machine. Still today, even after decades of operations with no incident, there are still people in the industry that argue otherwise... The most telling example is the high speed derailment in Santiago de Compostela, essentially due to the fact that the driver is considered a good enough guarantee to drive a high speed passenger train up to 200 KPH... Sigh.

Not in the daily lives of the vast majority of Americans.
The three train systems I've used on a regular basis in the last half decade (NJ Transit's NE Corridor, Amtrak's Northeast Regional, and Caltrain) very much do not have driverless trains.
Two of those are in the top 10 commuter rail systems in the US.
I'm ranting here, but you're on an undeservedly high horse.
http://www.uitp.org/sites/default/files/Metro%20automation%2...
There has been 1 accident in 30 years attributed to driverless rail mass transit control system, despite millions of kilometers travelled and a constant worldwide growth. Yes, rail has understood what driverless safety means. You may call it a high horse but driverless /is/ a high horse. That's my point.
In a way, your comment confirms this success. You think it is easy because you are used to it at an instinctive level. And that is the goal, precisely.
But it is not as simple as what you imagine. For instance, trains have multiple degree of freedoms. As an illustration, train builders calculate carefully the dynamic enveloppe of the cars (e.g. its worst lateral deformation due to bogie flexibility) and check against the tunnel walls geometry.
http://www.railsystem.net/structure-gauge-and-kinematic-enve...
> I don't think the majority understands what safety means in mass transportation.
And inferring that you meant that rail understands safety, generally, better than any other mode of transportation which I took issue with. I believe you 100% when you say that only one accident in 30 years ahas been attributed to driverless trains.
What I find horrifying about rail is how simple PTC should be: "am I exceeding the maximum speed for this stretch of rail? is there a train in front of me? if yes to either, slow down" and yet Amtrak says it will take billions of dollars and decades to install. I'm thinking of accidents like the NE Corridor derailment in 2015.
PTC is a problem of ROI for operators. The incentive is apparently not so great, so it will take decades. Also, and this is frequent in rail, any complicated solution that will leverage the existing infrastructure will be explored, further entangling the situation. In more controlled economies, the state has enforced for long the technology to be used. [1] Some may say it is a case where free market cannot be trusted to take the correct decisions. It is a societal debate, no longer an engineering topic. [2]
[1] Not too bad: https://en.m.wikipedia.org/wiki/Positive_train_control
[2] https://en.m.wikipedia.org/wiki/Rail_Safety_Improvement_Act_...
> the derailment was caused by the train's engineer (driver) becoming distracted by other radio transmissions and losing situational awareness, and said that it would have been prevented by positive train control, a computerized speed-limiting system
The second you put the train in the open air where other people are, where weather is, where nature is, those things kill people on the regular.
Get out of your tunnel, and suddenly your "success" has nothing to do with the control system.
I don't want to sound obnoxious but driverless metros routinely operate in the open air :). Tunnels are not a mandatory condition for such systems. They manage strong winds, strong rains with reduced adhesion conditions, etc. They manage the possibility for people or non-protected trains to intrude on the track. A lot of brain was put into automating decisions related to fire scenarios or emergency evacuations. Metro lines like Paris line 1 are extremely busy. There are plenty of ways to kill people, yet they don't. Just the "stuck hand-bag" scenario is a nightmare to manage. Yet.
A driverless system is truly a massive piece of software. You guys should come in the tunnels and have fun with us!
This is demonstrably false. There are many metro systems with tracks on viaducts and at-grade (e.g. "open air"), with GoA 4 control systems.
These systems can and do detect objects on the track. They also deal with severe weather (heavy thunderstorms, snow, etc).
I think you're discounting the experience of delivering railway systems without considering lessons that could be learned in deploying them, and applying that to self-driving cars.
> If you substitute, you have to do much much much better. Nobody will ride a driverless vehicle provided the explanation that it is, you know, "already an improvement when compared to a typical driver". Is it fair? Maybe not, but that's the whole point for entrusting lives to a machine.
I've heard Elon mention this and while I don't know exactly it's measured, he claimed that fully autonomous cars would have to be 10x "better" at driving than a human before they would be allowed. I'm paraphrasing when I say "better" but I'm sure I could find the video of him talking about it.
At any rate, your comment is interesting.
I don't know where Elon gets his numbers from, but according to EN 50126 practioners, human error is in the range of 2E-4 / 1E-3 whereas safety functions are classified at least SIL2 and that means 1E-6. In other word, the system must be x1000 better than a human.
Here is a good reference: http://en50126.blogspot.it/2009/10/safety-integrity-levels-s...
If human flight was possible, surely they would have done it hundreds or thousands of years ago.
Your argument disregards not only advancement in theoretical knowledge, but also advancement engineering in the form of computational power and sensor sensitivity.
In the case of establishing the correct position of vehicles, whatever the technology used it will have an error of measurement. This error accumulates over time, especially if you are measuring displacement. You will need reference points to retain your positional uncertainty within an acceptable value. An autonomous vehicle uses a map containing features that can be used as reference points and triangulate its position based on that. A human brain does this constantly using its eyes, ears and memory. It is an example of diversity: you correlate the perceived displacement by your internal ear with what your eyes sees, using a reference learned in your brain about your surroundings and sensors' ability.
To reach 1E-9, we cannot rely on such self-learned things: we can agree that the probability for the landscape to change is quite higher than 1E-9. In the case of trains, driverless trains use coded beacons / loops or GPS diversity. Such techniques imply that the infrastructure around your vehicle collaborates to the safety of the system. Hence my statement.
This being said, the rail industry has been dreaming for long of a completely vehicle centric solution. There are high stakes for that: reduced costs, competitive advantage, etc. Last attempt here: http://www.alstom.com/products-services/product-catalogue/ra...
On the bad side, this risk culture destroys large scale innovation, and even safety in the long run. The problem is that we've adopted an attitude that safety is always first, meaning that it is immoral to do something in a less safe way, no matter what the other benefits might be. This means we get a regulatory, tort, and engineering culture that is willing to use existing systems, because they are grandfathered and therefore "reasonable", but will only adopt new systems if they can be shown to be perfectly safe.
This culture is fairly new. I date it to sometime in the seventies. Ralph Nader and the Pinto were both symptoms and causes. You can see the transition in, for example, how America responded to the Apollo 1 fire vs. the Challenger accident.
Since you're a a rail engineer, let's look at rail mass transit systems. The NYC subway has a limit of roughly 30 trains per hour, a two minute headways. All of the braking rates, margins of safety, and signaling systems do their job, and you never see two trains hitting each other. During rush hour though, trains are packed way over capacity, and this is mostly because of this headway limitation. If you were to imagine this on the freeway, you'd have to leave two miles between you and the next car. The cost for this level of safety is that about half a million people have to spend an hour every day in miserable conditions. Many of them choose to drive or take cabs instead, to avoid this.
When they make this decision, none of them even give the slightest thought that driving is maybe 10x more dangerous than taking the train. They understand that safety for both is plenty good, and the way that they spend two hours of their day, 13% of their waking hours, is a lot more important than some tiny difference in their risk of dying on the way to work.
Ultimately, while very well intentioned, this safety culture is inhuman. It's pessimistic. It says "nothing in your life could possibly be so important that it's worth any possibility of you being injured. "
So, this is what we face now, over and over. With self driving cars, it's, "sure, the chance of you getting killed is half as much as if you had driven, plus you get all of that time back to have a nice conversation, read a book, or idly stare out the window, but since it doesn't meet our aviation/rail transit level of safety, you can't have it." You even see it with kids -- your twelve year old kids can't be allowed out of the sight of an adult, or you're a dangerous, neglectful parent. It does not matter that childhood is the process of learning how to be an adult, and that becoming an adult is a process of progressively mastering greater and greater freedoms -- the most important thing is that we are never seen to expose children to even the most minute level of risk.
I really want us to have a real conversation about acceptable risk, informed consent, and human progress. We need it badly to regain our souls.
So true. Its an issue in General Aviation where there has been huge progress in safety devices (electronic cockpit gauges, airbag seat belts, etc) but it has been illegal to install them in older aircraft because of the FAAs very slow, expensive certification process. Finally, in the last year or so, the FAA got serious about what's called "Part 23 reform" which will vastly streamline the process for safety upgrades in older aircraft.
Also, I don't want this comment to be interpreted as shitting on the FAA. I'm a libertarian leaning former liberal who generally has very low confidence in our government but I consider the FAA, with their insane safety record of which I'm a massive fanboy, to be a exception.
I've posted variants of this same comment several times and I'm starting to feel like a broken record.
Look at studies of efforts to make planes safer by removing the human element. While efforts like autopilot have made things safer it reaches the point where more automation can reduce safety as pilots are no longer alert and/or don't trust the instruments and/or can't fully manually override the automation.
Call it the uncanny valley of automation safety.
Bridging that last few percent for true automation (ie where vehicles aren't designed to have drivers or pilots at all) is going to be _incredibly_ difficult, to the point where I'm not convinced it won't require something resembling a general AI.
All of this is why I think driverless cars are going to take much longer than many expect.
One example is the attack on the Chicago air traffic control system. Dozens and perhaps even over a hundred aircraft suddenly were flying around with no oversight. Every single pilot took local control, negotiated with the other pilots, and collectively were able to either land or divert without incident.
If this had any element of truth roads would be empty.
This kind of sweeping and bigoted dismissal of other people is a bit too self serving in the context of self driving cars and is made too casually and too often on HN now to allow balanced discussion.
The other thing is that something going wrong with a plane in the air is a pretty big deal. You can't just pull over and wait. If you assume a "first, do no harm" principle of robotics for driverless cars, the failure mode should in most cases by "pull over and wait." This can still cause problems in many situations, but people do it now.
Er, citation needed. I think the vast majority of drivers are good drivers — otherwise, vehicular transport would be a disaster.
"Good drivers" -- we have no benchmark to measure against. Maybe it's amazing that 10x more people aren't killed, or maybe it's dismal that anyone is killed at all. When we have autonomous vehicles, we'll have a reference to compare against. I predict that "bad" will be the only word to describe the current situation.
[0] https://en.wikipedia.org/wiki/List_of_countries_by_traffic-r...
Countless times I've seen pedestrians or cyclists throw themselves in front of traffic without warning, and every time the drivers have stopped without incident. A collision is by far the more exceptional case.
I am not disputing your assessment, but please don't discount liability. Planes can pretty much fly themselves today - there are no significant technology issues with the idea of "taxi away, take off, fly to destination, land, taxi to gate". all of this happens in what is perhaps the most regulated traffic environment on the planet.
The issue is with creating the code that deals with "oh shit" scenarios. Whilst is is probably possible, and even feasible, to write code to cover every possible failure scenario, who is going to be left holding the can when this fails (all systems have a non-zero probability of failure)?
Who will be held responsible? The outsourced company that coded the avionics/flight control software? The airplane manufacturer? The airline company? The poor fucker that wrote the failing logic tree that was supposed to deal with that specific failure scenario, but was forced to work overtime the 47th day in a row when that particular code was cut?
It is a liability nightmare, and when you add up the cost of creating a software system that must never fail, the increased insurance premiums, the PR/marketing work to convince the unwashed masses that this is actually safer, and the whole rest of the circus required to make this a reality, you will find that pilot costs are not all that bad. Especially since pilots have significant downward pressure on real earnings these days anyway.
but
> The issue is with creating the code that deals with "oh shit" scenarios.
So they fly themselves except they don't?
That's kind of my point: what makes anyone think truly driverless cars are going to happen anytime soon when a human is required to deal with these "oh shit" scenarios? What's more, I think the "oh shit" scenarios for cars are FAR more complicated. With planes someone else deals with scheduling for take off and landing. While in flight, the plane simply needs to not fly into other objects and maintain speed, direction and altitude.
As for liability, I agree. It's a nightmare, particularly when the standard will probably be "did the software cause injury or death?" when the standard should be "what is the incidence of injury or death compared to a human driver?"
I mean that'll be little comfort to the family of someone killed in an accident. We humans seem to have a weird tolerance humans negligently killing other humans.
Really? If anything I'd have said it was the other way round. Humans get jailed for negligently killing other humans with vehicles, and they sometimes get jailed or banned from driving for negligently driving in a way that might have endangered another human. On the other hand, the prevailing opinion in this thread seems to be that whilst it's entirely appropriate to punish bad driving by humans, similarly egregious errors made by software should be tolerated provided their average accident rate is lower than the humans'
Recovering from the "oh shit" scenario is the difficult part, but human pilots often can't recover, after all it makes little sense to try and fix an engine on fire while flying, instead opting to land.
It's not. But it's a reasonable first reaction which is why we end up doing it. (That or swerving.)
But as soon as we realize the thing that made us twitch is a squirrel or a plastic bag, our forebrain takes the foot off the brake or straightens the wheel.
No, but you can ditch an engine that is on fire.
> instead opting to land.
That is supposed to be the outcome of any successful flight.
Autoland is possible with an engine out, even at low altitude (on final approach):
http://www.askcaptainlim.com/flying-on-the-boeing-777-flying...
So as far as the software goes that's business as usual and not even an 'oh shit' scenario.
It will be particularly interesting if accident blame is placed on the 'dumb cars', and then insurance companies do a 180 and charge MORE for 'dumb cars' operated by humans. Once they put this information in their pricing models, I assume its 'stuck' in there until the next major NTSB report is published.
As complacency sets in over a couple months & years, the accident rates will likely swing from "dumb" human operated machines back to "Level 4 Highly Intelligent Teslas/UBERS/Argo AI", and that market might get a real shock when the pendulum comes back their way!
An advanced AI may well be able to identify whether an object coming towards the windscreen is a bird, bat, leaf or a rock, but what will its intuition be about how much of a problem it is likely to be? Should it swerve to avoid a raccoon and risk whiplash for passengers? Should it aim to avoid large insects if the owner is vegan?
Also, people are very used to mild lawbreaking. We expect a cab driver to double park and let us out the car if there are no available parking spaces, but would an AI be authorised to bend the law or would it have to find the nearest parking space, which may be 5 blocks away and could be taken by the time it gets there?
I suspect we will get autonomous drone-like flying cars long before we get full autonomy in city centres or rural areas, because flying through a mostly obstacle-free space with an ability to avoid collisions on 3 axis seems much more reachable?
Only if the other cars on the road around it are also owned by vegans.
Thankfully this isn't as big of an issue with driving on the ground. Airplanes don't have sensors that give them the same precision as a car's wheel rotation or proximity to nearby objects.
Cars don't operate in a comparable problem-space.
E.g. I would quit too.
Is exactly what was written above.
I am one of the biggest Tesla fans out there. I fucking love the company. But Autopilot in its current form is nothing short of dangerous.
I took a test drive in a Model S a couple months ago and enabled Autopilot at the Tesla rep's encouragement while on a straight stretch of route 90 near Boston. We were going 70mph, a safe speed.
The car came to a point where the highway curved, and a slight deceleration is required to navigate the curve correctly.
Little did I know, Autopilot stays at the speed you set and does not alter it as the environment requires, short of not hitting the car in front of you. So of course it tried to take the curve at 70mph and swung out of the lane almost instantly, prompting immediate corrective action from me to avoid a serious accident.
I couldn't believe the Tesla rep hadn't made this clear. I was required to have my hands on the wheel, but the position of my hands doesn't ensure that I'm mentally ready for egregious errors on the car's part and prepared to correct them at a split second's notice at all times.
Operational question mark aside, as an investor I was also astonished that the software was still in such a rudimentary state that it didn't know to slow down on curves. I found this troubling. It was scarcely more advanced than cruise control, to be honest.
It's the one place where I think Elon is really gambling with people's lives as well as his company's credibility, the former being an infinitely worse transgression than the latter.
Tesla uses a combination of the visual lanes, cars in front, and an accelerometer, to determine the curve and how much it needs to slow down.
Other than a freak situation last year (not on a curve, it was the hill crest with the white truck crossing the highway), every SINGLE accident has been shown to be the drivers fault with autopilot disengaged. Not a single accident of what you described has happened.
But it is not 100% false that the Tesla I test drove functioned this way. It is, in fact, 100% true. This happened last month.
Can you provide a map link to the stretch of road where this happened?
This almost killed a tester from the German federal motor vehicle approval agency. Their overall report is devastating, and shows the Tesla autopilot is little more than a glorified cruise control, marketed in a very deceptive way.
https://github.com/andrew-ayers/udacity-sdc/blob/master/Term...
Then again, it does have a failure mode where occasionally, for some reason, it will direct the car to change lanes into the path of a much faster moving vehicle in the lane being changed to. Most of this is because it only runs the behavior planner every second or so in the simulation, and probably does get everything perfectly correct in the prediction part (I honestly am not sure where the problem lies, though).
That means if you're on the Autobahn, at say 130km/h in the right lane, and a Porsche is coming from behind at 300km/h, the Tesla will not be able to see it, and consider the lane free.
Normally I'd call the issue "the driver", but since the car was automated, it was an input failure, not a curve that couldn't be negotiated at that speed.
I do agree with his goal. And maybe its worth some percentage of Tesla buyer's lives? Let's not talk too much about this, okay?
Is this video online?
We used to treat our test pilots with the highest regard. How low have we fallen?
I think this is an extremely salient and important point, and I've never thought of it before!
Test pilots only care about a good product, not success or failure of the product. That's not the case anymore.
Maybe this would be a good time to propose a new "test pilot core" for cars, made up of perhaps some elite drivers who don't work for any car company.
Or heck, maybe the army wants to test self driving cars!
Yes, having more neutral testing programs like CA's standardized testing would be nice, particularly if the tests were mandatory for all manufacturers.
I'm surprised there isn't a national testing system in place for that, but I guess it is our system to leave most control to the states.
Not sure who cares about version here. Your airplane went down? Yeah, should be fixed now, no worry, try the new version!
The previous system (HW1 or AP1) is a MobileEye chip, which is found in most other cars that also have "lane keeping" features. They all use the same chip with the same model provided by MobileEye, and can choose to overlay features on top of it or augment the system with other sensors (such as radar on the Model S/X). For that system, it is essentially the same performance whether it's a $150k Tesla or $30k Honda.

"With autonomous cars, you see these videos from Google and Uber showing a car driving around, but people have not taken it past 80 percent. It's one of those problems where it's easy to get to the first 80 percent, but it's incredibly difficult to solve the last 20 percent. If you have a good GPS, nicely marked roads like in California, and nice weather without snow or rain, it's actually not that hard. But guess what?

All quotes pulled from this article (which is really quite good and you should read it in full):
https://www.nakedcapitalism.com/2016/10/self-driving-cars-ho...
Just driving around New York City for a while makes me think that generalized autonomous driving, as a problem, is essentially "solving" strong AI. Consider the case of approaching a complex intersection during rush hour. There's a traffic cop in the intersection waving his hands around. You reach the intersection, the light is green, you want to proceed straight, but cars are blocking the way because they're backed up into the intersection on the cross street. The cop points directly at you, making eye contact, blows a whistle, and shouts at you, pointing and yelling "right right right". You're uncertain whether he means you should try to weave around the blocking cars, but he blows the whistle again and it becomes clear he is telling you you cannot go straight, and you must divert and make a right turn right at the intersection. He gestures again, indicating that he wants you to turn into the nearest lane on the cross street, then points to the car behind you and indicates that it should also turn, but into the center lane. You nod, and he looks away to another car.
This happened. So a self-driving car would presumably have to understand and interpret shouted commands, realize that they are the one being shouted at by someone with the right authority, recognize gestures, somehow be able to engage in the equivalent of recognized eye contact, be able to make an OK gesture, and have some sort of theory-of-mind about the traffic cop as well as the drivers of other cars.
Not easy.
Needless to say, not a situation for "auto-steer".
I'm sure this has been thought through, and I imagine the solution involves zones requiring different levels of autonomy and capability, some means of zone discovery or classification for unmarked areas, and self-driving cars refusing to continue automatically when overmatched.

We have a law that airbags have to accommodate unbelted passengers: http://www.iihs.org/iihs/sr/statusreport/article/35/6/1
Now sure, a passenger can be different than the driver but it's the same philosophy.
The amount of illegal maneuvers I see every day on my commute is astonishing - not using blinkers, intruding on cross walks, not moving over for emergency vehicles, following too closely, etc. It doesn't help that the only traffic law enforcement is really around speeding / running red lights / DUIs.
The problem with autonomous cars isn't the autonomous cars - it's accommodating non-autonomous actors. It only takes one google car hitting an old lady who's chasing a duck on the street to become CNN breaking news for the next 3 months a la that airliner that disappeared.
Probably quite a good part of the $hundred of millions price of a passenger plane is the autopilot (even 1% means $1M). And even at $1M/plane, 99% of a plane's autopilot works because it assumes that the current plane is the only one in a large vicinity of a point in space. This is assured by a centralized third party (control tower) that is not really automated but a very stressful human job (that's why the air traffic controllers are well paid). This is not the case with cars - in this case, most of the work being done is having each of the individual cars detect, with complex but not very good sensors and software, what is around them, in a swarm of other moving objects that do not communicate.
Electric power assisted steering. Few cars on the road currently are correctly termed steer-by-wire. Actually, only the properly-optioned Infiniti Q50 comes to mind.
You can still break when the ECU does something stupid. You can still break if you loose vacuum (engine not running), it's "just" more harder to do so.
Lane departure warning and collision warning systems are pretty prevalent. And even autobraking collision avoidance systems are getting pretty widespread.
As we now know, all of them are cheating.
(Also, "having more ethics" sounds really strange in my ears. "... being more ethical than those at <XY>"?).
