Our image among the cycling community is one of "rogue" users. As I think about all the things that cyclists can do to improve our image-- stopping at a red light seems the most visible and by extension the most powerful.
Here's a radical proposition-- for those on the fence about stopping at Reds-- consider that the best time to stop at a red is when there are the most people watching you. The synergy there is that you are making a statement to the broadest possible audience. Furthermore, stopping just might encourage a few other cyclists to stop-- increasing the image of cyclists being nice.
I look forward to your thoughts!
