I mean is there an actual electronic connection or is it done wirelessly. I just saw on TV that Toyota may be using throttle by wireless and I was wondering if BMW does the same thing. I used to work with wireless, and let me tell you, if that's the case, I have no trust in the technology whatsoever. :thumbsdown:
If I'm wrong- my car is for sale-

its called drive by wire, the same technology that is used on airplanes. there is no wireless in the accelerator pedal. someone previously had it right. there are sensors in the pedal that operate on a referance voltage, the further you press the pedal, the greater the change in referance voltage. the ECU reads that and converts it into a signal that is sent to the throttle as to how far to open. also, try holding your foot on the brake and try to accelerate. it should start to accelerate then shut the throttle down to avoid a runaway. this condition also sets a fault in the ABS system. I think it was called brake pressure sensor plausibilty-it basically indicated that the gas and brake were being pressed at the same time

I had a TOY-ota Prius. It was a great car. Much more utilitarian than the 550. However, it was uncomfortable and the interior was falling apart at 56k miles. The mechanics of it were fine.
I bet that Toyota's car will come out better after these problems because they are going to be hyper sensitive to resolving all the current issues.
