Car delivery drivers spend all day every day loading valuable vehicles on to and off of trailers.
Typically, they make loading the vehicles into tight containers look easy, but here's proof that it can quite easily go very wrong indeed.
In the video below, the truck driver lines up the 1965 Ford Mustang with the ramp and accelerates forward. The front wheels roll up straight and true, but as soon as the rear wheels hit the metal slope they begin to spin.
This sends the rear of the car off to the right, where it falls off the ramp and hits the side of the trailer.
It's unclear how the driver managed to get the car loaded in the end, or how much damage was caused by the mishap. However, it's probably safe to assume that the car's owner wasn't too happy...
