Track vs. Path
OverkillTASF - I think the best summary of this comes from ADVRider "abhibeckert". Track: Not paved, narrow enough to make passing difficult or impossible for cars. Path: Not paved and so narrow that even two motorcycles would have trouble passing each other.
Options have been proposed including tagging a single node to describe this, or breaking these sections of trail into two sections.
OverkillTASF - So far I don't much like any of the proposed ways of tagging this. It seems a bit too granular, but if someone came up with an elegant solution, that might change my mind.
