Oh this definitely has a 50+ component.
My son and I ride together right now. I am 50, he is 23. We take totally different routes we one of us takes the lead.
I am always trying to find a route that gets us off the 45-50mph roads. When he takes the lead he will take us right down the 45-50 mph roads.

That said, we have had close encounters on practically every type of road we have ridden on and when they come close it makes my blood boil. Sometimes I would yell at them, sometimes not.
I have since gotten cameras to record my rides. The cameras have put an end to the chance of yelling because I am too busy calling out the license plate number.
