Well, recreational routes and networks simply are not that organized, and 
jurisdiction or authority doesn't apply to most of them. I guess that is why 
the values are more generic. 

I still don't understand why you tag "US" while it's obviously a bunch of roads 
in the US. or Interstate when the road clearly crosses state lines. I think 
that"s more redundant than tagging "we classify this route as a regional 
route", even though it might cross two national borders in a few places and 
half the roads are outside our borders, and we don't know the current operator 
or provider.
