I always have a laugh when I see Copenhagen brag about its cycling infrastructure (e.g. Scandinavian Airlines declaring it bike-mecca in their flyers). I am very sorry, but it really doesn't come even close to Amsterdam, or most other Dutch cities really. There are a tonne of places where high-volume car traffic still intersects with low-speed bicycle traffic in Copenhagen, a lot of high-speed car roads with painted on lines, instead of actually separated infrastructure.

Also, the Netherlands is in its entirety covered in separated infrastructure optimized over decades. Just take a look at how anemic Denmark's infrastructure is outside the cities (https://www.opencyclemap.org/).
