Pretty good article in TIME from BSNYC about Bike to Work Week.

"Alas, if anything, the greatest hope we cyclists have for Bike to Work Week is that it might make a few people into more considerate drivers. Sure, most of these riders will probably return to their cars next week anyway, but perhaps some of them will do so with a little empathy and a better understanding of their own behavior behind the wheel."
