The story is that Brad saw the red car parked very strangely (picture 1), blocking in another car. His guess is that the red car slipped out of gear, rolled backwards and hit the car behind it (picture 2).
When he came out later, the red car had been moved (picture 3) and ticketed (the little white thing on the car’s windshield). Apparently the authorities came along and pushed the car back into a spot. Sort of. It’s definitely bad parking when you forget to use the parking brake.
