Denmark has a separate infrastructure for cyclists and walkers too. It's quite wonderful. Like a quiet, peaceful break away from the noisy roads. The cyclist roads lead to all sorts of nice, nature-filled places too, and are used for just taking walks in the nature.
The biking roads are one of the few things I truly commend Denmark for.
Also the biking roads next to the car roads are usually proctected by the borders... like... the side-stone or whatever you'd call em and usually has a patch of grass in between. Its a clear mark between whats car road and whats not, thus making it more safe. It's not just some marking on the car road itself.
The only really dangerous places to bike, are at the intersections. Always makes me nervous.
Edit: Found this EPIC cosplay...
