I've yet to own a drive by wire car, and after reading this, I don't think I'd really want to.

i hate it, the engine feels entirely disconnected. the only benefit is for gm'* cost cutting and they try to make it out to be this big technological marvel.

Yeah I've changed a lot of the throttle position sensor covers on the new gen V8 engines, have never heard of a concern like yours though of the vehicle wanting to take off like that. There'* 2 throttle position sensors in the throttle body for safety purposes, if one doesn't agree with the other it will set a P2135 and put the vehicle into reduced engine power mode.

I just don't see what the advantage (if any) would be from a drive by wire throttle. Throttle cables are relatively inexpensive, durable, and simple. I think it'* more like having technology in a car for technologies sake, and is just one more thing to fail that is more complicated, and expensive to repair than it needs to be.
