From The West:
“The guy was reversing and he decided to open his door and hang his right foot out, with his left foot on the accelerator,” he said. “Maybe he couldn’t see properly so he had his head right out of the door.
“You know how you don’t have as much control with your other foot? Well, he’s accidentally floored it and just catapulted onto the other car.
“It’s really mystifying. The curb is sloped and I think he just hit it at pace and got airborne.”
“The leg that was dangling out got caught between the tree and the door, unfortunately,” Mr Perry said.
