It's All Your Fault: The DOT Renders Its Verdict on Toyota's Unintended-Acceleration Scare – Feature

The DOT concluded that, other than a number of incidents caused by accelerators hanging up on incorrectly fitted floor mats, the accidents were caused by drivers depressing their accelerators when they intended to apply their brakes. “Pedal misapplication” was the DOT’s delicate terminology for this phenomenon.

The Senate Commerce Committee has also scheduled a Sept. 6 hearing to ask why the National Highway Transportation Safety Board waited so long to act on the problem, calling NHTSA, Ford and Bridgestone-Firestone officials to speak.

The NHTSA says Ford knew it had a serious problem at least a year ago, when it began replacing Firestone tires on SUVs in the Middle East. Firestone and Ford tire controversy.
