Indeed! I have not found any evidence nor have much personal experience to support the idea that lots of bike lanes/paths/etc. imples a bicycle safe or friendly community. I recall reading someone's study showing that the most common bike/car accident is being right hooked, followed by being doored. Being hit by a car overtaking is (as I recall) quite rare. Does anybody have any imperical evidence supporting marked bike lanes? Or the opposite, does anybody have any imperical evidence showing marked bike lanes to be as dangerous as sidepaths?
