I was with a friend in a 5L V8 Mercedes, and we were doing a quick drive around the block after some sort of maintenance. He floored the accelerator - I can't remember why that was required, except I assume it wasn't. I assumed he was only going to do it momentarily, but the car rapidly reached, and passed, stupid speeds for that road. Just as I started to say something about preserving lives of us, and anyone else on the road, he suddenly shifted to neutral and brought the car to a stop with the engine screaming away at the redline. He then calmly reached down, unjammed the accelerator, and then continued driving back home.

That car was automatic, but he drove cars with manual transmissions a lot, so that would make it an obvious thing to do. I think in some of the famous unintended acceleration crashes, it has been unclear whether the person tried to change to neutral. A lot of newer cars have a much less intuitive method of doing so as well.

There's nothing as good in this regard as cars with manual transmissions though, in terms of having a dedicated pedal which disconnects the engine from the wheels, which you practice constantly during daily use.
