I learned something form this:
http://blogs.consumerreports.org/cars/2009/11/video-how-not-to-stop-a-runaway-car-dont-pump-the-brakes.htmlDON"T PUMP THE BRAKES. The problem is that most brakes are vacuum assisted, and if the engine is at full throttle, there is no vacuum. There is a small vacuum reservor, but this is quickly depleted if you pump the brakes. I never knew this. They also recommend turning the key off, since htat can lock the steering wheel. The best bet is to put the car in neutral. The throttle limiter will keep the engine from blowing (but if you are in a run away situation, a blown engine is really not your biggest worry).
Which brings up several interesting questions. Many cars do not have ignition switches any more. They have power buttons. How do you turn off a car with a power button? (Hint, just tapping it doesn't do it.) Cars like the Prius have a shift by wire transmission. How do you put one of these in neutral?
I think Toyota has a bigger problem here than bad floor mats. I think they may have a fundamental flaw in there design, and unfortunately some of these modern conviences like power brakes and smart ingitions and smart transmission really are creating very dangerous situations.
Interesting that VW has some further smarts in the car that appreantly sense when the brake is being pressed and back the engine off. I think that needs to be a requirement on all cars. It should not be too hard. If the brake is being pressed for more than a few seconds and the engine is revving kill the damned engine.
