Hahahaha .... good one! You obviously have not ridden the streets in Raleigh, NC. I know how to trip a traffic signal in theory. In practice, there are several on my route that will not trip for a bicycle, period. It doesn't matter how I position my bike or how long I wait. The light won't change unless a car comes along and trips it.

BTW, back to the original post, I try to abide by traffic laws, but will run traffic lights that do not trip. I also treat many stop signs as yield signs, after looking both ways twice. However, there are a couple of intersections on my route where I always wait for the light to turn green. They are too large, busy and dangerous to cross without a green light, and the sensors actually work at these signals.
