If you're going to do a U-turn while you're driving, it's probably a good idea to check the traffic before you do. The video from Dash Cam Owners Australia shows a driver who forgot to look to their right and ended up slamming into an oncoming car.
Next, this driver in China doesn't seem to understand the concept of giving himself space as he backs up. Three times in a row he collides with a small wall. Being stubborn, he backs up incorrectly a fourth time and rips his bumper off. He also fails to notice practically everything else around him.
