My car is clutchless.
But it still has the clutch pedal.

I rigged the clutch pedal to a very large physical disconnect.

If I ever have a problem with the car, turning the key one click disconnects the main contactor (and doesn't lock up the steering.)

In event of an emergency, I can stomp on the clutch pedal, and it will turn the whole traction system off. (Also keep thieves from stealing the car, as the first thing the typical manual transmission drive does is push in the clutch.)

When I was doing the "test until failure" stage of testing on the original Open ReVolt, it finally failed right when I started the car in a parking lot.

Seems to me that if a controller is going to fail, right when you turn on the main contactor is a likely time. Kinda like how light bulbs usually burn out right when you flip the switch.

I always start my car with the gear selector in neutral. If the controller did fail, so what, you are parked, and just flip the key to off.

Jyanof, when your controller failed, were you already moving? Was it right after your turned your car on?

Learning how things break is the best way to learn how to improve them.
