a reverse acelerator in case you fall asleep driving
 

the problem now is obvious you fall asleep and you keep pressing the acelerator

so the solution:

a reverse acelerator you press with the TOP of your foot NOT THE BOTTOM

A 'reverse accelerator' in a car normally calls itself 'brake'. Weird, isn't it?

Great idea, now I can use long drives to catch up on sleep.

there are some complex solutions to this problems like this:

the acelerator in my idea is OVER the foot and you RAISE the foot to accelerate, on this way when you fall asleep you just stop acelerating

Doesn't help, as you can fall asleep and keep pressing the throttle down.

You could also just stop and take a powernap.

thats the trick you PULL the acelerator UP, since the acelerator IS OVER YOUR FOOT,so when you fall asleep you relax and stop pulling the acelerator with your foot

im sure if there were lorry drivers around they would apreciate this idea

It would ruin the top of your shoes, and your foot is more sensitive at the top. It would hurt.

Instead; An adjustment to your original idea: The accelerator works the same as it does today EXCEPT that the top part of the accelerator gives you maximum speed, and pressing all the way down gives the slowest speed. What could go wrong with that?

You try lifting your foot up against a pressure,within a short period of time you will be straining and cramping up muscles and tendons--daft idea.
Ok ,you fall asleep and stop accelerating ,i assume it must be locked into the steering somehow as well.;)

What's to worry? You'll stop eventually.
