Yeah, Sort of like this but the one above was moving. https://www.roadandtrack.com/news/a...owbird-porsche-911-falls-off-car-transporter/
A very tricky operation that. You have to back up the Porsche just enough to clear the back edge of the level the vehicle was being transported on, but obviously not too far that the back wheels roll off. I would think there should be some wheel chocks in place at the end of the ramp. (This ramp lowers to the lower level kind of like an elevator....)
