Bike lanes barely change cyclist risk at all, "sharrows" increase risk: http://cyclingincities-spph.si.../2012/06/TeschkeVeloCity2012.pdf

Huh, I had no idea that "sharrows" were supposed to mean that the cyclist was supposed to ride in the center of the lane, as though they were a car. The actual behavior I've seen is that the bicyclist rides as though there's an imaginary bike lane running along the line of the sharrows, and the car drivers swing wide into the opposite lane to pass them, since there's not actually enough space for a bike lane there. It has always seemed kind of dodgy, but people get awfully religious about the role of bicycles on the city streets...
The most religious seam to be the most oblivious.
No surprise at all that sharrows make biking more risky. Nobody knows the rules for them, and people do stranger stuff than if a bike was just riding along on a regular unmarked street because they're confused.
