A Different Spin on the Dangers of Urban Cycling

Two recent studies appear to expose cyclists as a potent urban menace.

Bicycle riders pose a danger to themselves and to pedestrians, according to the studies. Bicycle commuters have 2.3 times the black carbon, or soot, in their lungs as do noncyclists, according to a U.K. study whose results were applied to cities world-wide. And each year in New York state alone cyclists cause about 1,000 injuries to pedestrians that require a hospital visit, 55% of those in New York City.

These widely reported numbers look very different when put in context. The carbon figure was based on only a handful of cyclists in London. And the injury figure appears less troubling when cast alongside trends in New York City cycling: The number of cyclists has nearly doubled since 2007, even as pedestrian injuries have fallen slightly.

Neither study has been published in a peer-reviewed journal and each was preliminary. Yet each one was cited in media coverage that depicted the results in ways the authors didn’t intend.

    These so-called “studies” are so full of the simplest of flaws that they don’t deserve to be called “scientific” at all. In fact, if a freshman handed in a paper like these, he would be given a “F”. Yet, these so-called “studies” and their “results” are widely published without any mentioning of the flaws. Thanks to the WJS for exposing these flaws.

I' d really love to hear from y'alls!
