It is not because of this, but because Amsterdam created entirely separate bicycle routes that have grease separated intersections with main roads for cars. So they simply don't have as many traffic lights for bikes because of that. Also, even if the are traffic lights they're much smarter at adapting to traffic and have much faster phases than in America.

> avoid any intersections with other users and flow interruptions: people should not cross streets, they should pass over them on bridges.

No, the cars should be the ones going over bridges or through tunnels. Doing it the other way around is prioritizing cars and dehumanizing pedestrians and cyclists.
