Last weekend, about a mile from our home, a rider on a well paved, single lane, rural FL. road, decided to pass several cars on a sharp, blind curve, he ran head first into a on coming car & was killed. Never heard if he had a helmet on but in a head on, at passing speed, I doubt if a helmet would have helped much..... Note: I am a strong believer in wearing a helmet & never, ever ride without one BUT if you're a adult and don't wear one, that's your choice.
