I'm in favor of reducing speed lines, but I don't think that is enough. I haven't seen a city with more bikes (or where cycling works better) than Copenhagen, and it's full of bike lanes (the vast majority of them proper, segregated bike lanes, not painted, of course).

Which cities have you cycle in to compare them with Copenhagen? (Assuming you did actually cycle in Copenhagen).

Madrid, Barcelona, London, Paris, Berlin, apart from other smaller cities in several countries. And yes, I also cycled in Copenhagen. Have to confess I haven't been to Amsterdam, which is also considered an extremely bike-friendly city, though.
