In the audio, the LAB reveals that 1/3 of all cycling deaths are due to rear end collisions. Also something near 50% of all car bike collisions are reported as the fault of the motorist.The League of American Bicyclists estimates that at least 700 cyclists are killed in U.S. traffic accidents each year. and the New York Times reports on an increase in deaths of cyclists and pedestrians after a 5 year decline in New York, that echoes a national increase in traffic fatalities altogether.
The LAB also seems to firmly believe in more bikes are better... safety in numbers.
NPR also has some Ghost bike stories...
