Anyone that does not operate as a vehicle is asking for a one way trip. Running red lights is about as clever as taking a toaster in the tub with no GFI.
I personally stop at all stop signs & red lights. Also... i keep many eyes out at merging & yielding spots, and where lanes multiply at intersections, i stop before rail tracks & listen, i always let a bus go before me, i never go on a yellow light, i always stop for pedestrians & always glance around before making a move that isn't a straight line, and i always communicate my intent where possible. I also often walk bike across at the pedestrian crossing, because legally vehicles have to yield to pedestrians, also it can be quicker than waiting for a light. Riding is a privilege, and i treat it as one.
When in doubt, take the high road out.
