Years ago we used to provide brake rotor and drum turning services to the many independant service shops that used to be near us. Sam was a constant customer of this service so he would just pull up out front and walk in with his rotors. This day was no different except Sam was driving one of his customer's old cars. Killing two birds with one stone he said, test driving and picking up parts. Since the old car had a problem warmed up he left the car running out front on fast idle. We were at the back of the shop when suddenly there was a VERY large crash and glass came flying through the shop. We looked toward the front of the shop and saw Sam's customer's car slammed into the front of the building partially through the closed overhead door. Nobody was in the car and the doors were still closed. We could not figure out what happened until a guy came across the street from the motorcyle shop yelling "FAR OUT MAN" He then told us that the car backed out from in front of our shop and he thought the car was going to crash into the light pole. About that time it did crash into the pole, crushing the rear of the car. The car had an automatic transmission with a worn out floor shifter. The vibration of the high idle caused the shifter to drop into reverse and the car flew across two lanes of traffic slamming into a light pole. The impact of the reverse crash caused the shifter to smartly move into drive and back across the street it came slamming into the front of our service department. All the time not a sole in the car. Sam had to explain this to his customer, no one was driving your car and but it wrecked itself both front and rear in two separate accidents. Oh and by the way your car damaged the new car dealer's building and destroyed the dealer's overhead door.
