Heck, look at the idiots who can buy a tractor and can't figure out how to run it. Why they could kill someone. Their victims could die laughing when they read that the operator can't hook up a mower or sharpen blades, they put gas in a Diesel, run over the dog, have to ask the wife if its too noisy, can't fix a flat, turn a wrench or charge a battery. Yep, more people killed this way than in gun fights....
