I am a cycling addict, I ride for about an hour a day. However, I find cyclists who don't respect the needs of those who share the roads to be an annoying menace.
In my own riding, I try very hard to stay near the side of the road (i.e., out of the way), I don't assume drivers will yield to me, and I work to stay aware of everyone around me. It is a minimum of courtesy and also safer.
