Daniel Duane in today’s New York Times cites San Francisco Bicycle Coalition’s Leah Shahum, who says that no motorist has ever been prosecuted for killing a bicyclist, assuming the motorist was not intoxicated and did not leave the scene. We don’t know how many of the hundreds (677 in 2011) involve motorists, and how many involve bicyclist fault. But surely something is going on here. We are aware of the ongoing hostility between some bicyclists and motorists, a feeling that Duane suggests is shared by law enforcement. This is creepy.
