The number one cause of unintended acceleration is that a driver has his foot on the wrong peddle. It's extremely important not to lift your foot off whatever pedal it is on, because chances are you are mistakenly pressing the accelerator. The people who run the auto web site edmunds dot com got really frustrated with how nutty the discussion of sudden acceleration had become. If anyone could prove that the car was the culprit in sudden acceleration, that is an explanation differ from someone hitting the wrong pedal or a floor mat trapping a throttle, edmonds would pay them a million dollars.
