Randy Cohen, who teaches the world how to tell right from wrong with his NY Times Magazine column "The Ethicist" is an avid cyclist, and Streetfilms recently accompanied him as he rode around town holding forth on biking dos and don'ts. Cohen abhors the presence of motor vehicles in the park ("Seeing a car in the park is like seeing someone pelt the Mona Lisa with mud!") and adores NYC DOT chief Janette Sadik-Khan ("She's increased the supply of human happiness in NYC and she's done it while speeding up traffic flow.") But the best part is when he weighs in on the ethics of running red lights:

"I'll deny this in court, but I almost never stop at a red light except when I might endanger another person or myself," explains Cohen. "I slow down, look both ways, and go through the light. What are we, Germans?" So there you have it: stereotyping the behavior of an entire nation—perfectly ethical!
