What are the chances of a controller failing both the e-brake and throttle cicuits at the same time causing a run away vehicle?

I posted about it in another forum so here is that link.cut off switchMy exact concerns are for a bicycle but it applies to all I imagine. And, lest not forget the Toyota Prius!

well, slim, but possible.

if you are worried, you could short two of the motor phases.

it will lock that wheel up like you wouldn't believe, but it'll stop you no worries.
thats the cheapest way.

the less cheap way is to crowbar the battery to blow your main fuse.

the next cheapest way is to use a big enough contactor.
