Without question cyclists are the nerdiest/quirkiest of all those groups. Today my wife and I did a 15 mile road. The route was mixed between subdivisions, bicycle lanes and dedicated bike trails. The dedicated trail is wide enough to go 3 riders wide, but it's tight. When I ride with my wife I ride beside her. I pull ahead of her or drop behind her when a rider comes from ahead or behind. I keep my head on a swivel and go single file well ahead of the arrival of another rider.
Today I looked behind me and saw another rider coming. When he was several hundred yards back, I pulled in ahead of my wife. He passed about a minute after I did and said "ride single file." Not sure I heard him right I asked "what did you say?" He said "ride single file." I laid into him. "I was single file you dumb mother ffuukker." He snarked back "you weren't" I said "I singled up well before you got here you goddam dumb mother ffuukker."
Meh, it wasn't any skin off my back telling him what I thought. I asked my wife if that embarrassed her when I said stuff like that. She said not when you say it to an idiot mother ffuukker.
