HN is a pretty critical place most of the time but sometimes it's valuable to take a step back. The challenges associated with building a car that can drive itself are pretty insanely difficult (even something as straightforward as "how do we get the training data?") and the fact that we're now at a point where there's a possibility of self-driving cars working in snowy conditions is pretty awesome.
I've seen the demos of the start ups in the valley, the local experiments, but i'm still waiting for a single real-world deployment, even limited to local driving, such as city to city taxi driving, or item delivery.
On the other hand, i did hear of the trouble with tesla's autopilot "2" not driving properly on regular roads under the sun (https://www.youtube.com/watch?v=UZ1XLqc5IUg).
There are self-driving cars that drive themselves well in clear conditions, but these are the R&D cars with an expensive sensor suite on the roof and a bunch of processing power in the trunk that can't be found in production cars.
That's still more money than not having those components in your vehicle, for sure, but that's well within luxury car territory and costs are still coming down rapidly.
Demanding a probability of zero can make anything impossible. And you're not even asking for zero fatalities, you're asking for zero "issues", whatever those may be. That is a wildly unrealistic demand. Human drivers are not that reliable either, especially in bad whether conditions.
90% of the way to true "self driving" is plenty to revolutionize things.
Isn't that basically what @usrusr was refering to? People who rely on the autonomous driving so much that they basically forgot how to drive themselves?
