Ah yes, I remember reading that.

My potentiometer has the micro-switch, which COULD be used to turn the main contactor on and off as you press or release the accelerator.

I do NOT have it hooked up that way. To me, that always seemed like overkill. And a lot of going "clack clack clack".

If you have the pot micro-switch rigged to the main contactor, that means that you already have the car in gear when your activate the main contactor. (Right? Why would you press the accelerator unless you wanted to drive?)

If you have a device that fails in the ON position, and it is most likely to fail right when you turn it on, and it gets turned on by being in gear and pressing the accelerator......

Hmm. Just doesn't sound like a good policy.
All gasoline cars are designed so that they have to be in park or neutral to turn them on.

An electric car should be the same way.

(In this case - "ON" means having the controller activated and connecting the main contactor.)
