It's been rough to watch a relatively new email list, Bicycling Advocacy, torn apart by the usual bike lane-vs-no bike lane debate. But Ken Kifer said something interesting recently: "I don't agree with a policy of ignoring problems caused by motorists." Simply teaching bicyclists how to ride in a vehicular fashion, and prosecuting those motorists who illegally assault or injure bicyclists, to me is ignoring a much larger problem. Call it the increasing motorization or freewayization of our streets if you will, but traffic calming, as well as bicycle and pedestrian facilties, properly done, are an attempt to stem such a tide.
