> All it takes is paint and a few bollards. From all that I've heard, an effective change requires far more than that. For example, the bollards do make it one step higher than a "bike gutter", but how does the city clean leaves and trash, or snow, from the lane if the normal street sweeper and snow plow can't get in due to the bollards? Instead, you'll need specialized equipment for the lane (or bike lanes which are wide enough for cleaning/clearing equipment), and the political will to not prioritize cleaning the car lanes first. You can't have bollards at intersections, so you'll end up with drivers using the bike lane as a turn lane, and turning across a lane without noticing that a cyclist is there. With a road redesign you can build in affordances which encourage better interactions than you get with mere paint.
