Passed a single speeder on a downhill and fought the urge to ridicule.

Then I was being a good "vehicular" biker on campus by not flying by all the cars stopping for students in crosswalks. Of course they didn't care to jaywalk in front of me when I had a left turn light. About 2 minutes later was waiting behind a car again and heard a squeal of tires and realized that I was 2 inches from being rear-ended. Closest thing I have to an accident in 4 years of commuting.
