This graph, from the Atlantic Magazine, shows that as the number of cyclists on the road increases (the example given is NYC), the number of accidents with automobiles decreases.

This evidence ought be a rally cry for more bike lanes, bike paths, sharrows, bike parking, bike lockers, etc in the CLV; in sum all things that faciliate bicycling ought be implemented with due haste in Cleveland.  Our city's roads were constructed to handle  1,000,000 and we are at less than half that!  It's time to put some roads on a diet!
