The risks associated with cycling decrease dramatically when more cyclists are on the road, and especially when those cyclists obey traffic laws. This second point is hammered home in this bizarre but brilliant 1963 bike safety film, “One Got Fat” (the eagle — or is it monkey? — eyed among you will have recognized a clip from this film in the Freakonomics video “Does Sport Cause Crime“).

One thing “One Got Fat” doesn’t mention is helmet use — helmets weren’t widely used until the 1970s, and controversy remains over how effective they are in reducing bike fatalities. (Full disclosure: I bike to work whenever possible, and wear a helmet, an adherent to what a few cyclists I know like to call the Cult of the Styrofoam Talisman.)

Hahaaha that video is funny.
