It's inevitable that we are going to be driving by wire. That's why EMI - Electromagnetic Interference - will be playing an increasing role in cars' safety and reliability. My gas pedal was stuck, too, on my Camry 99. It wasn't a sudden acceleration. I just couldnt accelerate at all. However, it was quite scary, too.

Another aspect of EMI problem is quality of instrumentation that automakers use. We may have some very serious issues over here. Time will tell.

It all boils down to whether a natural process can cause a resistive short such that (i) the computer doesn't pick that it has occurred; and (ii) that the resistive short acts to accelerate the vehicle. It is amazing that Toyota's engineers and Exponent's engineers aren't aware of a naturally occurring process that can cause a resistive short in tin plated or soldered electronics. Such resistive short circuits due to "tin whiskers" have been found in Toyota's accelerator pedals!!!!!

EM interferrence due to increased cell phone use as well as other wireless signals both man-made and natural occuring, I'd never want to drive a car without a cable to both the gas and brake. Most airplanes can fly-by-wire incase of emergencies and cars should be the same.
