I don't really grasp your analogy but your definition of advertising is not complete. Advertising does indeed include messages to increase product/brand awareness. It could be argued that in most advertising, this is actually the case.

Reducing the cost of getting your message to the market without changing your customer acquisition rate is by definition not a zero sum game.

kerryfalk··on The Most and Least Expensive Cars to Maintain
You have to put a big turbo, 3mm seals, and suffer turbo lag, etc. almost any car can get a lot of power with a turbo but N/A power is the place for me.

I'm rebuilding my S2000 right now turning it into a 2.4L stroker for 300+ hp. :D

FD's are, not so sure about their older counterparts the FB and FC. I had an FC. ;)

This isn't what happens, though. As others have mentioned, the engine ends up under the car.
kerryfalk··on 25-year-old lived for more than a year without a heart
Admittedly I didn't read the whole story, the click-bait title got me.

I had a girlfriend with a similar device attached to her (an LVAD). At first it was a little unnerving seeing her unplug the batteries that were keeping her alive and charge them every night. It quickly became normal for me. Life with it seemed relatively normal except she had to have a purse with her at all times (it carried the batteries).

The interesting part was when she received a transplant and went cordless. After being attached to it for two years and not having a heartbeat the sound of her heat beating kept her up at night for a couple of weeks. I hadn't even considered the beating of a heart to be relevant to our daily lives until she had mentioned it once she heard hers beating again (an LVAD is just a constant velocity pump. The blood is always flowing).

Not sure how much it really adds to the conversation other than an interesting anecdote.

Many trucks are owned by the drivers and not part of a fleet. I don't know what the ratio is nationally but I can say locally it's probably in the range of 50%, maybe even more are owner-operators vs. company fleet. So this pricing model would make sense to target that market.

kerryfalk··on What It’s Like to ‘Wake Up’ from Autism After Magnetic Stimulation
Agreed. Everything I read that he said I can relate to. They are feelings that if presented with the same situation I think I would probably feel.

I read this story thinking about how difficult it would be to go from not feeling it, to feeling it. I've spent decades learning and adapting, he had no time. That would certainly be very overwhelming.

There are a lot of tech nerds in motorsports.

Sorry, you're misinformed on what ESC and traction control do, it seems, and the rhetoric makes for a difficult conversation.

I didn't take them, I taught them.

We call the driver aids "nannies" in motorsports because they fix some driver errors. They limit control and input. They don't react for the driver. Interesting fact: A driver can out-brake ABS. The vast majority of motorsports competitors do regularly.

I'm not sure why I'm engaging in this, I should probably have more coffee... :)

HN Is a lot more combative with posters making broad assumptions than I remember.

In that hypothetical situation I might wish that they had taken some high performance driving courses from me or my colleagues/friends. And spent time behind the wheel of cars at the limit, as I have, so that they had better skills to potentially avoid the accident they caused (with or without ESC).

ESC doesn't save people from bad driving, it masks some of their errors.

There is nothing wrong with disabling traction control. Please don't use the ESC in your car as a crutch. It won't save you.

kerryfalk··on It's a Tesla
You're right.

I will not be changing my behavior. ;)

kerryfalk··on It's a Tesla
No one is at risk. Most people should not disable the nannies. ;)

Even at idle the turbo is spinning. Engine RPM at highway speeds isn't vastly different than engine RPM at city speeds (perhaps a few hundred RPM in the average car). Therefore turbo lag also isn't vastly different.

Variable vein enables turbos to match engine speeds more quickly. Greatly reducing turbo lag.

C Class AMGs start around $80k.

?

The M4 is basically an M3 - they've been around that price range for quite a while. What else can you obtain with similar performance numbers and fit and finish for "way less money spent"?

We're veering off topic a bit but I've come to learn Mercedes pretty well now. I'd put money on your feeling with the Mercedes being two-fold: 1) The gearing: They're long gears and it defaults to selecting a very tall gear. I have 500hp on tap and doing 50mph in 7th gear isn't fun, but that's what it selects as a default in comfort mode. 2) Traction control: It might not be as much of a problem in non-AMGs but the traction control is surprisingly intrusive and very good at hiding that it's engaging because there isn't a mechanical coupling to the drive wheels. It uses the brakes and I assume some throttle limiting. Even in the sport handling modes it's quite intrusive.

I never drive with traction control or in comfort mode - not even in winter. It's a completely different car with them off - if you get another chance to drive one I'd suggest turning it all off. Unfortunately the throttle isn't linear but any more than 20% will spin the tires.

I also have an S2000. It has half the horsepower and weights 1,000lbs less but it's a blast.

A turbo is a better driving experience on the highway.

How so? I would perceive no difference between a turbo'd engine and a Naturally Aspirated one while driving on the highway at a constant speed. Engine responsiveness as per the parent poster would be the same within the city vs. on the highway.

There is no way to "solve" turbo lag.

I'd suggest researching variable vein turbos. BMW has done it very successfully in their e92 335s. Even resulting in a flat torque curve at very low RPM. It's impressive engineering.

kerryfalk··on It's a Tesla
The CLK430 has a 275 HP V8 and the car weighs nearly 4,000lbs. That's not a lot of power for a vehicle of that size and non-AMG models aren't geared for acceleration. The surge you experience is probably the transmission down-shifting. On typical city driving the Mercedes transmissions seem to select gears 2 higher than what would be optimal for acceleration. In the AMG models they don't even use 1st gear unless the transmission is in Sport mode.

Glib solution: Buy an AMG and smile when you put your right foot down, but cry when you go to the bank...

C63's default to comfort mode. They don't introduce any lag in comfort modes, they simply select a higher gear than what would be ideal and up-shift at lower RPMs (1,800RPM in a C63).

Source: I own a C63 and my startup procedure includes completely turning off traction control and putting the transmission into S+ every time I get in the car.

kerryfalk··on It's a Tesla
Guesses as I don't know which specific models you're referring to:

The parent's lack of throttle response is most likely due to turbo lag. Modern cars are getting better with variable vein turbos.

If your Mom's Mercedes suffers from poor throttle response I'd guess it's because she purchased one with a small engine relative to the size of the vehicle. A C230, for example, isn't the sportiest of cars. A C63, however, does not suffer from poor throttle response.

kerryfalk··on It's a Tesla
The new C7 'vette is leaps and bounds ahead of the previous generations. It's not the same as you might expect from other performance vehicles in terms of fit and finish but it is quite a bit better than what they used to produce and you'd be hard pressed to find a better bang for your buck.

With that said, I personally chose to spend more for a very boisterous German muscle car...

kerryfalk··on Tesla Intrigue Deepens with Musk's Twitter Barrage
On that topic: the selection of the driven wheels probably matters less than people think. The most important factor is the tires. Want winter traction? Buy winter tires.

In modern cars Active Stability Control (ASC) is effective in eliminating oversteer, no matter what the drivetrain setup is. Traction at stop lights would favor RWD when a car has near 50/50 weight distribution (I don't know what the Model 3 is but would guess it's close).

RWD makes the car simpler and with modern ASC is no less safe for the average driver than FWD. I'd guess that traction in a Model 3 would slightly favor RWD but tires matter more.

kerryfalk··on Tesla Intrigue Deepens with Musk's Twitter Barrage
Not true. I've always driven RWD and have competed in National Amateur racing events with the SCCA (and taught high performance driving techniques at my local club).

I setup my cars with a heafty amount of rear toe-in (1/4"). When the weight transfers left/right or one of the rear wheels hits a bump/hole it will push the car in one direction similar to torquing one side of a shopping cart with your hand.

A RWD setup allows the car to be more efficient with its tires (using one set for turning and one for power vs. one for both). FWD is just seen as safer because most people panic when a car oversteers. As the saying goes among driving enthusiasts: "Oversteer scares passengers, Understeer scares drivers"

kerryfalk··on Model 3 Unveiling [video]
The P85D is a massive step from a base Model S in terms of performance. It has super car levels of performance.

I wouldn't be surprised to see a Model 3 with something like a P65D besting M3/C63 performance numbers.

"I am not racist or anything, but 100% of them in Geneva are black - that's 5 years of experience"

...it doesn't seem far of a stretch to make the leap to using your statement here to indicate that you may in fact be racist.

There was no reason to indicate their race, so why do it? Did they have blue eyes, too? What can I infer from shady blue-eyed people on street corners selling me drugs?
