AFAIK that distinction was always made by width (or width for the
access-points, e.g. if they are blocked by boulders you won't be able to go
there by car anyway)

many roads in Europe might not be safe to pass in the winter time (or some
might not be safe to pass in the summer time, see "winter road" discussion
from the Russians). This doesn't make them less "public roads"

yes, but there are other tags to use than the highway class that can
express in greater detail what might be the problem (e.g. surface, width,
smoothness, lanes, ...)

what about adding unmaintained=yes?
> It is different rendering that is the point here
yes and no. Yes, the rendering should preferably distinguish between paved
and unpaved roads, and no, the highway class should not be chosen by the
rendering rules of a certain style.
( And this discussion should probably be on the tagging list, but I've
still not added that to my catalogue )
+1, crossposted to tagging, please lets continue there
