I stop for most red lights but there are a few that I don´t. For example when going through a light and immediately making a right turn onto a bike path. In this case although I am technically going through a red light, I am not crossing the intersection so I am not doing anything dangerous. Sometimes it doesn´t make any sense to wait at a red light. My priority is to get safetly where I want to go in the shortest time.
Since the traffic system is built and designed primarily for cars I feel justified in exercising a little discretion at times. Compared to the dangerous stuff that cars do all the time, anything I can do on my bike is just insignificant IMO.
