Noah Kazis of Streetsblog brings us the somewhat counter-intuitive fact that bike share riders are involved in fewer accidents than bikers using their own set of wheels.
From Paris: "In 2009, the most recent year for which data is available, Vélib' riders were responsible for one-third of all bike trips in Paris but were involved in only one-fourth of all traffic crashes involving a bicycle."
And from London: "...no people were seriously injured or killed on the first 4.5 million trips on Boris Bikes, while about 12 people are injured for every 4.5 million trips on personal bikes."
