"... Oftentimes, they don't trigger traffic lights to change, because many run on inductive sensors buried in the road (the reason for all the "Dead Red" laws in the map above)." This drove me crazy when I lived in Seattle. Many of their lights would never turn. So I would have to get off my bike, walk over and press the button. Now that I live in NYC, Idaho stops are the norm where nearly everybody, including the casual cyclist does it and tickets are few and far between, it not only takes my commute from 15 minutes to (literally) 4 minutes, but I feel safer because I'll usually leave a huge pile of traffic behind me with a clear road around me for blocks since they stop at every light and I don't. Of course, NYC has a 25mph city-wide speed limit, so that helps dramatically. I think the most important thing here is being obsessive about looking for cars and yielding appropriately. If you fail to do that and are a daredevil who just blindly runs out into traffic, which I see fairly regularly, you are putting your life at risk and potentially others around you as well. Edit: Looks like Seattle just passed a dead-red law last year! Now if they would just classify electric skateboards as bicycles like California did, that would be spectacular.
