I had a safety light on, bright neon vest, and blinking helmet light on my black cannondale in boston on a rainy day. A car slammed into a row of parked cars right next to, sending a guy in one of the through the windshield. The car then took, so I chased it to get it;s info, and they pulled over and got out of the car wasted in some format, telling me they were just looking for a place to pull over, and then when they figured out my outfit merely approximated a bike cop outfit and wasn't one they took off. But by that point a million people had their license plate numbers. All the witness though I was a cop too due to my really pretty ugly/crazy get up. so if people see you and think you;re a cop that can't be bad from a safety perspective.
