Hehe, I'm afraid I don't share the optimism that cycle lanes improve motor vehicles' passing distance. 😇 My personal experience suggests the opposite: Drivers think as long as they stay just left of the cycle lane they're good, leading to very close overtaking. Also, 2-minus-1 roads suggest that driving on cycle lanes is okay, which is counterproductive.

Luckily, we don't have to agree on road-marking policy here. 😉 Please forgive me for having taken the discussion a little off topic.

Back on topic, I'm curious: What difference would we expect from bicycle routers for the two lane tags?
