We went recently for an oil change. The technician pressed the accelerator while pressing the brake pedal while putting the vehicle into reverse. The vehicle lunged into the parking lot. Fortunately, there were no vehicles behind my vehicle. If the technician had been shifting from neutral into drive, he would have driven into the building. The technician said that…
