I wrote a blog post to show and explain the many improvements to the “Straßenraumkarte” that Alex @Supaplex030 worked on for the last few month: https://supaplexosm.github.io/strassenraumkarte-neukoelln/posts/2021-12-31-micromap-update
With this public space map for Neukölln, Berlin Alex continues to push the boundaries of the level of detail that can be rendered based on OSM data.
The blogpost shows many interesting details like cycleways, turn lanes and junctions and explains how the data is processed to allow this rendering.
One conclusion is, that a collaboration on pre-processed OSM data for streets would be a huge benefit.
