When working on HOT tasks, I often see these structures tagged as
highway=track. This is probably contrary to the primary definition in
the OSM wiki as "agricultural", but matches with the more common
language usage of a "mark left by something that has passed along."
A more "proper" tagging might be highway=unclassified, surface=unpaved.
But I'm not sure that is of additional value as it implies to me some
kind of formal road-ness that is not reconcilable with the informality
of such tracks.
