I live in suburbs between San Jose and San Francisco, and haven't driven in a while but on a typical car trip I see someone run almost every other light at busy intersections, seeing a motor vehicle come to a full stop at a stop sign is rarity as well unless there is a law enforcement vehicle watching. I have learned to wait after a light turns green for me defensively to make sure someone else has not decided to gun it and run the light.
