This is even better by letting the cars do the vertical movement, while the bikes stay on flat ground.

  Possibly but images like this an be misleading. As the article on the floating roundabout points out it's not all that high above ground, the junction itself is below ground level. The cars are in fact doing most of the vertical movement. The floating roundabout does have the disadvantage that you need a bigger height difference to allow the cars to pass below it.

    I know both the "Berekuil" as well as the "cycle roundabout" as they are both down here in Eindhoven. The Berekuil is nice, but very confusing as to what direction to go as you no longer can see the roads once you are down in there. The floating cycle roundabout OTOH is fantastic as you keep having a great overview. It really is a marvel of engineering. The slope is not a problem on either of them for the average bicyclist in the Netherlands. edit: Just noticed that the referenced Berekuil above is another one in Utrecht. I meant this one [1] [1] https://en.wikipedia.org/wiki/Berenkuil,_Eindhoven https://en.wikipedia.org/wiki/Berenkuil,_Eindhoven

      There is yet another in Arnhem, the "Airborneplein" is also nicknamed Berekuil.

  Bikes also have some vertical movement there, but it's hard to see in the perspective.

    And making bikes go down before an intersection is a terrible idea because cyclists are extremely keen on preserving inertia when they know that it's going uphill soon. When an intersection is raised, yielding becomes almost zero-cost.

Here's a similar solution in Malmö https://www.google.com/maps/@55.5648378,13.0021608,801m/data=!3m1!1e3 https://www.google.com/maps/@55.5648378,13.0021608,801m/data...

  Ooh, three levels! Makes sense that the bikes don't actually need a roundabout to manage traffic.
