I wish I had a quid for every "racing" driver I'd heard quoting that one and then exiting through the tyre wall! Lots of people (myself included) can make themselves do the right thing when practicing. FAR fewer can actually DO it in a genuine panic situation. As for me, well, I just don't know - I've never been in a situation where I was a split second off killing someone!
I know of not one person who can do the right thing in a real emergency, but can't do it in practice. Statistically, such people must exist, but I doubt I'll ever meet them.
In any case, they exited through the tire wall because of Risk Compensation; that is, most of them forgave themselves in advance of crashing through the tire wall because they consider the lower potential consequences as an implicit permission to perform a riskier behavior.

The problem is that there will always be older cars around. My daily drive is a modern company car with all the electronic keep-you-on-the-road gadgetry. My own car is 17 years old and has a (fairly crude) ABS system but nothing else. If such behaviour were to become so deeply ingrained in me as to be second nature in a genuine panic situation, I doubt I'd then be able to change it depending on what I was driving.
Better driver training and education would not only have raised the nanny-bots performance standards, but it would encourage most drivers to avoid the use of such techniques for the very reason you point out.

Earlier 2-channel and even some 3 channel ABS systems were pretty lousy. The most modern ones (at least in Europe - I haven't driven any American cars lately) are (at least in my view) pretty good.
The only non-4-channel ABS systems that have exceeded my standards were for the Chevy Caprice and the Ford Crown Victoria - both were obviously developed for police pursuits. Most Euro cars with ABS, even in the 90s, were up to my snuff.

I can't think of any manufacturer that would do that! The problem with under / oversteer is not the amount of effort required to turn the wheel so it wouldn't solve the problem!
Exactly. The problem isn't to make it easier for the driver to do the right thing, it's to make the driver do the right thing. Oh, wait, sorry, I meant the car, not the driver. It's to make the car do the right thing, and make the driver pay for the markup each time, rather than pay once for the training.
It seems to me that the cost-to-profit ratio of installing 'safety' systems external to the driver apears favorable to those who are more directly concerned with money - car companies can afford to spend more money adding 'safety' features to each car, since we'll pay for it again each time we buy another car, so the math works out - for them. If however, you were to invest the cost of 'installing' ABS/Traction Control/Stability Control/EBA/ etc. in each driver, that driver brings that improvement to each car driven going forward at no additional cost. More importantly, their children aren't brought up to be such maddeningly risk-averse wusses.

There WAS a time when the driver was expected to do his own ignition advance via a control on the steering wheel too - but I've learned to let the car do it for me now with no hard feelings!
The car controls ingition advance better than you can - not just more consistently, mind you, but more subtly. A good servo-nanny's average performance should also consistently exceed a good driver's performance.
Keep in mind that good drivers are a minority. That's why I'll never drive a Lexus; I can consistently exceed their Traction and Stability Controls - heck, until the mid-naughties, I could exceed their 4-channel ABS's threshold braking. (I've never liked Toyotas, mostly for that reason.

... The point I'm trying to make is that in a really severe crash, the laws of physics and the psychology of raw terror tend to make it impossible NOT to transmit significant forces into the wheel! During normal "spirited" driving, I completely agree with you that "hanging" off the wheel is not condusive to good steering feel but I still don't agree that emergency braking on its own - no matter how good the brakes are, would be likely to cause the torso to hit the steering wheel - even with no belt at all!
As a passenger, I've personally witnessed drivers who hit the brakes, and consequently make contact with the steering wheel. If the car had subsequently made contact with the hazard ahead ... None of these drivers had any clue how hard their cars could brake.
Perhaps this isn't a problem in the U.K.?

The thing I don't understand about "risk compensation" is that safety features on cars have been getting incorporated almost since the dawn of motoring and KSIs have been falling (fairly steadily) for many years too. Why haven't we just "risk-compensated away" all the safety improvements over the years?
Risk Compensation isn't the only force at work, of course. Since I am not a scientist, I will merely suggest that the only safety features which truly work today
A) either do so regardless of the driver's understanding, or in fact benefit from the driver's lack of same
B) do not give the driver any sense of empowerment to believe that the activity is safer due to the presence of the feature
As another example, even though I consider ABS (presently) the most important safety feature since the seat belt, most automotive experts disagree with me; they say it's Stability Control (the lovechild of ABS and Traction Control).
According to the 'experts', drivers would:
1) not steer after panicking with the brake, perhaps expecting too much from ABS's threshold
2) exaggerate steering corrections, leading to Newton effectively taking over
3) detect ABS's hepatic feedback pulses, think something was wrong, back off the pedal, and give birth to EBA
In this case, Risk Compensation simply killed the compensators themselves. In other words, ABS didn't save lives because it was misunderstood and misused (like seat belts, I say).
However, it isn't as if better driver training and education is some sort of unfamiliar devil ...
Amerikan (and I suppose other nations') law enforcement received enough training to properly use it, which is why it only showed a lifesaving benefit for law enforcers. (Rather than educate the rest of us, it was decided to make us buy more and more safety features.)
Stability Control, on the other hand, appears to have saved lives without any additional training. In other words, it's idiot-proof. How much of a good thing is that, really?
Seat belts, on the other hand,
tend to saved drunks, while also
tending to kill pedestrians in exchange. (It is unclear how many sober jack@r$e drivers killed pedestrians as either a direct or proximate result of wearing their seat belts.)
I believe that if the seat belt had been 'sold' to the public as a way to increase their ability to avoid or mitigate accidents, that's exactly what would have happened.
