    I was entering a major highway from a parking lot when the engine suddenly accelerated at full speed. Visibility was good. There was a small pothole so i did touch the accelerator. Next i was in the middle of the highway & hit by a car going 65mph. I do not think i hit the accelerator rather than the brake although that was the only explanation at the time. *tr

    Within the first year of owning my 2004 prius i experienced unintended acceleration. In the old days (i'm 71) if you experienced unintended acceleration you would right off check your gas pedal and floor mats. That kind of problem wasn't all that uncommon when you owned old cars. If you didn't find a problem in the area of the gas pedal you would pull off the side of the road and usually find the throttle spring on…
