@scott SFMTA's rollout was terrible, but the center lanes have really won me over. They make it really easy to pass (or be passed) and I think they are much safer than side running lanes for various reasons.On the side lanes, you often have pedestrians walking into the lane without looking. I've even heard pedestrians remark on how much safer they feel from "dangerous cyclists" on the center lanes.Cars turning right without looking is a much higher issue for side running lanes than center.
