I had a '64 Chevy truck. It became energized early one morning. While in granny low, it crossed the street and t-boned the neighbor’s car. The police woke me up, hoping to bust me for DUI. The only thing that saved me was a neighbor who witnessed the event. She told the police there was no one in the truck when it collided.
The cop talked to a few mechanics and finally agreed with the witness.
It can happen. The truck was 39 years old when it went out on its own that morning.
