Interesting! To me the best bike "lanes" are not lanes at all, they are bike paths through the Forrest, no cars allowed or even in sight. Paths like this [0]. The air is clean, it's safe and relaxing. When taking my kids to school I go over such bike paths, it's nice, I don't have to worry so much about the kids. Then we hit the road again, I'm breathing fumes, I keep telling my kids to stay at the side, tell them exactly where to brake and cross the road... We should separate cars from bikes as much as possible.
