Below is an argument that some people have used to complain about bicycles, slightly altered to reflect a bikers point of view.
Today when I got on my bike to go to work there were a bunch of inconsiderate jerks clogging up the road in front of me. They were riding two abreast, sometimes three abreast (when there was enough room, the things they were riding were like 5-6 feet wide each!). I don’t know what the occasion is, but every morning around 7 and every evening around 5 they have some sort of massive group ride. It should be illegal for them to all ride at the same time, it fills up the streets making it impossible to go anywhere, don’t these jerks realize that people have things to do?! I am forced to ride around them as they rudely take up the entire lane just for one person. I don’t understand why they don’t just use the highways, I mean the highways are designed just for them. I don’t understand why they are even allowed to ride on the streets, get on the highway where you belong! The worst part is there behavior, if you try to tell them to get out of the way all they do is honk their horn or give you the finger, I mean how rude!
