I blow through as many lights as I can. I feel it's my duty as a citizen of the planet to not sit idling in traffic wasting precious fuel and polluting the environment with toxic fumes. Apply some basic traffic flow concepts to the light systems here and I'll consider obeying the lights. It's pretty easy to tell if it's safe, you just open your eyes and look around to see if there are other vehicles, if you don't see any, you can go. Being that I've only had 3 tickets for the 3000+ violations, I think it't pretty safe to conclude the camera system here works about as well as everything else.

Cheers!
