How the Dutch Fietsstraat "Doesn't Exist"

I'm seeing some similar things happening in my City (Denver). They are creating a lot of neighborhood bikeways that just use existing calm residential streets. They are adding traffic circles at intersections, speed humps, and extra flashers for busy crossings. I really like the continuity shown in this video. That is the main thing currently missing in my city: you are often riding on a bike route that seems to just disappear into a stroad with just a sign telling you that there is no more bike infrastructure.
