Just because they could not handle it. It happened to many people, young people hndled that better.

It happened to me. I sure wasn't elderly. The only thing that stopped a crash was shifting into neutral and hitting the brakes.

Then, I was sitting there with the engine revving loudly for no reason. Car behind me started backing up. I decided to just shut it off and turn it back on. It went away.

Scary stuff. Especially since I had no idea why it happened.

How about a difference between Toyotas and non-Toyotas? It's not like elderly drivers are unique to Toyotas.

Also, unintended acceleration seems to have gone away. The control hardware has been changed; driver age, not so much.
