You cannot expect that any renderer will be able to display all
possible combinations of these three keys and dozen values. Or you map
is unreadable.

Excepted if you can provide a special device measuring the road
smoothness, it will never be objective. Forget the "smoothness" tag
please. We might replace it by the 4wd tag (but it's only a partial
solution) or another passable tag (for city car, 4wd, mtb, etc)
