An obvious rear camera cuts down on incidents like this, makes people be polite even when it's not in their nature. An Apeman SEEKER R1 not only records, but has automatic lights and calls attention to itself. I use an action camera on my rear rack, but use it to record some rides and not for protection. However I've noticed that cars are a bit nicer when they are being recorded, lol.
It's sad that people grow more short tempered and self-centered these days. Impatience with others is often a result of the person thinking what they want to do is more important than other people. I'm glad that good and friendly people still exist, and Saturday it was refreshing to come across several of them. I came across some people sitting on a bench near a bridge, and they were so friendly that I parked my bike and we talked for half an hour. One was a sweet elderly lady, and she insisted on a hug when I left. So there are some decent people left, and I just wish they were more common.
By the way, age is relative, and I don't think you're ugly OR fat!
