Frank Bruni has written a public thank-you letter to New York City’s Transportation Commissioner Janette Sadik-Khan in today’s New York Times. Sadik-Khan is a tremendous advocate for cyclists — she has roughly doubled the number of miles of bike lanes in the city since she was appointed in 2007. This article is a great read, thanking Sadik-Khan for what can seem like a thankless job and giving a nice overview of the current state of cycling in New York City. Make sure you don’t miss the graphic on the left, which compares the percentage of workers who commute by bicycle in major American cities. At 0.6%, New York City still has a long way to go.
