One of the joys of cycling, for me, is to be able to throw my legs over my surly steed and have pure, unadulterated and uninterrupted movement. It takes a lot of energy for me to maintain my 18 mph average commuting speed, and I am not going to sacrifice that because of a red light or stop sign. I never "blow" a red light, and in fact I always come to a complete stop to check for traffic. When or if the coast is clear, I continue through the red light with a smile on my face. Freedom. That is freedom on a bicycle, to be able to disregard traffic laws that have no utility in making me or anyone else safer.
