I've had exactly the same difficulty... tracktype/sac_scale/track_visibility/surface none of which capture the difference between a road a Toyota corolla could handle, and something that would be hard for a dirt bike to handle.
Difficult roads usually are so because of: steepness / lack of maintenance / clearance required / seasonal moisture. _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging
