I remember reading/hearing this somewhere:
When you're walking, you hate cars.
When you're driving, you hate pedestrians.
But everyone hates cyclists.
I would bet you heard that from a non-cyclist in Colorado. Personally I can't stand bicyclists around here, they act like they own the frikken road and, since they're conserving energy, being healthy, etc., they think they're way more important than anybody in a gas consuming vehicle. What drives me nuts is there will be a 4 lane busy arterial street with an empty 6 foot wide sidewalk on either side. Bike Bozos will be out using up one of the traffic lanes instead of using the sidewalk. It takes a lot of will power to refrain from clipping some of them with a door or mirror shot at times.
