I remember a big stink about this, I think it was 10 years back. Certain cars were being accused of "sudden unintended acceleration" and it turned out to be just people accidentally mashing the gas pedal instead of the brake. Car and Driver did a big series of articles on it. Certain cars got a bad reputation, I think Audi was among them, and they had a photo of a sign at a valet station saying they wouldn't park Audis with automatic transmissions.
