I'll always remember a time when a friend's mother was giving several of us a ride home from school on a rainy day. She pulled out from a stop sigh in front of a VW. My friend said, "Mom, there's a car coming!" Without looking, she said, "Oh, I can't see small cars." Obviously, she did see it or she would not have known the size. This, I suspect, is the cause of a lot of cage/bike accidents, damn idiot thinks, "Hmph, motorcycle. Can't see those." and turns anyway.
Pain is nature's way of saying, "We know where you live".
