In effect, the CDOT warning signs for pedestrians are disclaimers. To my eye, they are the city's way of saying to its non-cycling citizens: "You are on your own. Don't look to us to protect you by enforcing the traffic laws." It spells out what long has been going on. Think about it: When is the last time you saw a cop write a ticket for a bicyclist who failed to heed a red light or a stop sign? I never have, despite living just around the corner from Wells Street in Old Town. Sitting on my deck, I see dozens and dozens of bicyclists blowing through the stop sign all day long. At rush hours, all the spinning spokes and chains blend into a virtual scofflaw cloud.
