London has been doing a great job lately at improving cycle infrastructure. There is a new concept of a "cycle superhighway" - sometimes that means a segregated bike path, like CS3 that goes from The Tower Of London, straight through to Westminster, sometimes it is paint on the ground. However it is much clearer to motorists as they paint the entire line bright blue.

What I've noticed too is you get increasing returns the more you build. Given a scenario where a chosen route is covered 50% by acceptable infrastructure, it makes you think if it's worth taking a bike. Improve some strategic junctions and roads, and the coverage of acceptable infrastructure may increase to 90%, at which point it's a no brainer taking the bike.

In SF there are plenty of bike lanes that are painted a vivid green (the whole lane, with a white lane marker line). I think it's fantastic. It's really very difficult to not notice that the bike lane exists.
