The scariest story I've heard was a parked diesel pickup truck going runaway acceleration because of the hydrocarbon vapours in the air due to an industrial accident. They abandoned the pickup and it subsequently got blamed "A diesel pickup truck that was idling nearby ignited the vapor, initiating a series of explosions and fires that swept through the unit and the surrounding area". I read about it in one of the disaster reports about the Texas City BP refinery explosion. Ugly mistakes were made.
