My BIL is in auto body and he and his brother buy cars at auction from time to time to fix up and sell. I asked if he goes to this one. He said he avoids it because they drive the cars around too much too close to the crowds instead of just parking them and walking around them.
They average 1000 cars a week. No way to do that without moving the cars. They have a strict 5 mph policy. I suspect OSHA will make them install lolly columns in the lane to keep the car inside ( which would have prevented this ).
The driver has been there for years and has never had a incident before.
