I think motorway slip-road is "motorway_link"?

What is a slip-road onto something that is not motorway? Like a dual-carriageway
or, more unusually in the UK, a single carriageway. I would have thought that
highway = "sliproad" would have been better, and then reserve "motorway_link"
for flyovers and such like that just go from one motorway to another?

I have been wondering about this; what is a surfaced road that is not public
access? Unclassified seems to imply that it is public road (this is partially a
problem with OS maps, the inability to tell if a road is public or not).

How about highway=unclassified, private=yes? Otherwise, highway=private might be
an option, but I think that is more restrictive for future tags.

Thanks,
