This is pretty sad. The main reason I took up bike commuting is because I noticed I was getting too aggravated and angry when I drove my car to and from work because of other inconsiderate moronic drivers. The bike rides gave me an outlet and so far mostly cagers have made me angry. There were a couple of times another cyclist got under my skin, ie weavers and sidewalk riders who suddenly get in your path. But after my obligatory dirty look I usually let it pass right away.
