“The car was in acceleration mode at every speed on the highway, residential streets, at stop signs, always exceeding the speed limits. I continually braked to maintain control. Tires squealed when I released the brake at stop signs. There was nothing under the gas pedal. I didn't dare drive into the garage; the car would have been in the kitchen. When I put it in park, engine still revved.”
