LOL the entire City of Chicago is set up incorrectly then. No, if the sensors were that sensitive, motorcycles would trip them more regularly, plus bicycles would trip the red-light cameras and get the flashy lights behind them when I see them sail through without even slowing down. But heck, with no license plates or identifying marks on bicycles to track them to an owner, what do bikes even care of a picture is taken from a red light camera?
