That's the answer in a nutshell. Inside the nutshell there are divisions. My wife commutes on a bicycle, and I've learned a lot. She hates cyclists who ignore traffic signals and generally make cyclists look bad more than I do.Bicycles ! ....... they fly down sidewalks then switch to the road at their convenience, most have no idea what a stop sign is or a red light, they demand the right of a pedestrian at lights and crosswalks they are totally unpredictable and although they don't pay any road/license tax they demand bicycle lanes be built everywhere even tho' they only use them when it's to their benefit. I am a cyclist. I love my belt drive Trek but find that most of them are just dicks.
Don't forget the cyclist who ignores the multi-million dollar, barricaded, marked cycle path we built just for them to ride on the street with us.
