...we all know will self destruct the engine in short order.
 
Not sure where you got your info, but modern cars have rev limiters. You can put your foot to the floor in Park or Neutral and they won't go much over the redline. Some cars won't exceed 4,000 rpm when the transmission is in Park or Neutral.

Interesting and I don't doubt your knowledge on this, but I'll let someone else actually test the rev limiting functionality. When I want to shut down my engine for any reason, I want that ability right now....not delayed for 3 seconds. It doesn't seem to be an unreasonable request for drivers to have such capability, does it?

some of us think the smart gas pedal is a better solution.

That smart gas pedal might be a very adequate solution for stuck gas pedals but it only works when the car is in motion. It tells the signal to the brake to override the throttle control.
 
There might be a time though when the engine is running wild after an accident, and is pumping fuel through a broken fuel line etc even though vehicle motion is stopped. The obvious solution anytime you are involved in an accident is to shut off the engine immediately and that can be done only by directly opening the ignition circuit in gasoline internal combustion engines. If it is diesel then shut off fuel.
 
I still can't get hung up on the floor mats as being the root cause of these accidents. I've had cars for years that had floor mats that moved around sufficiently to sometimes get in the way of full brake and throttle action. I ended up securing them to the floor using velcro or cable ties to a floor post and that was the end of the problem. In the end I knew I could always shut down the engine by turning off the key. I used that the one time that the mat caused the accelerator pedal to become stuck in my driveway.

My comment had nothing to do with this subject. It was simply a thanks for alerting me to something I didn't know before. No motive other than to be gracious.

you really need to review the NHTSA report about this incident.
it would help you make more informed posts.
also, have you ever heard of an inertia switch?
these have been around at least since the early 80's when fuel injection became mainstream.
shutting off the engine cuts off the power assist to the steering and brakes.
smart pedal retains them.
i like that better.

Over on Prius Chat they have been doing exactly this. As corvette noted there is no chance of grenading your engine if you have a more modern one. The rev limiter works as explained.
 
At 80 mph the engine slows to idle and the vehicle slows down.

something you didn't know, but is it real?

As has been noted, this is generally not true for today's cars. Many will shut down the fuel pump, turn on the hazard flashers and interior dome light, and unlock the doors. Some, such as GM cars with OnStar, will automatically call 911 if the impact is severe enough.
