I admit not obeying traffic rules all the time when cycling. When I break rules I do so when it is safe. Often there is a choice between the rules and safety. Some bike lanes are unsafe and need to be avoided. Sometimes I break rules in the interest of conserving momentum, because building speed takes effort. I only do so when it is safe. As a cyclist I have a good view of traffic around me and I can often get off the road if necessary, which cars can't.

I'm not going to go through the red light when there are cars passing through... That would be stupid.
