This is just a six-second video, but it's enough to convince you that golf-cart horseplay is a bad idea.
In this security camera footage at what appears to be an apartment complex, a man is seen backing up his golf cart suddenly in a parking lot. As he tries to do a J-turn -- presumably as a bit of a stunt -- the cart turns over on its side. In the crash, the man, who didn't have a seat belt on because golf carts don't have seat belts, flips over at a slower rate than the cart. His face hits the roof of the cart as he falls to the ground.
And that's why you don't mess around with golf carts. One, you could get hurt. Two, someone could be watching and laughing their ass off.
