I looked at a few of the “proposed” bicycle ones. Their actual reality on the ground seems to vary a lot:
- Relation: Radroutennetz Harzkreis (405989) | OpenStreetMap appears to map parts that are actually signed of a proposed network.
- Relation: F5 Fietssnelweg Laakdal (Zuidzijde Albertkanaal) (13269186) | OpenStreetMap is complete except a few short parts (if the linked map can be trusted).
- Relation: 300 (17994660) | OpenStreetMap might only exist on paper
- Relation: 677 (12617174) | OpenStreetMap notes “The route along the MVC will change as the highway is built”. Does that mean it exists, but alternate parts need to be built?
