The brake pedal is a pretty obvious user interface. Most people use it whenever they drive. In general, brakes will easily overpower the engine when fully applied. Car & Driver did some tests to be sure [1], and were able to stop a floored Camery going 70 MPH in 190 feet, only 16 feet further than with the throttle closed. Even if shifting or turning off the engine aren't an option (doubtful) the brakes are an obvious and simple way to bring the car back under control. There's really no avoiding the fact that driver error, or at least inaction, played a large part in these accidents.
