Unable to answer "How many car lanes does this road have?" – Jungsøvej (Tertiary Road) – https://osm.org/way/415619126 via StreetComplete 58.2:

In Denmark, there's a lot of "2-in-1" roads popping up. There's only one semi-wide lane, but narrow enough that two cars can't pass eachother. On both sides there's wide biking paths, that are only delimited with road paint. All traffic can ride in both directions, and when two cars going opposite directions needs to pass eachother, they are meant to lean into the bike lane, and then afterwards return back to the center lane.

This video explains it pretty well, though only in Danish... The animation should be pretty self explanatory though. https://youtu.be/51azrFbUSFw
