I turned right into a driveway (at a low speed) with the brake pedal applied. Suddenly, and without warning, the car accelerated wildly, making a great deal of engine noise, as the throttle appeared to be wide open. Thankfully I hit a near-by tree and two front air bags deployed. A homeowner called the police, and an ambulance took me to the emergency room at a nearby hospital. …”
