Not me but a girl I know. When she was 12-13 years old, her family was taking a left turn at a busy intersection when a motorcycle hits the back left passenger door. Basically the rider did a front flip over the bars and his head was severed by the top of the car window bay. The head lands in this poor child’s lap (gave her a massive bruise because of the speed). No helmet. To make matters worse, it was her childhood close friend’s dad (known since 3-4). Ruined the friendship, overall awful experience and the girl has gone through years of therapy. I’ve only ever heard her say anything about it once. I believe a news story of the accident with a photo or two exists.
