Nice analysis :). But just because this may be "all you care about",
it doesn't mean it's an appropriate set of categories to use for

1) You gotta tag with verifiable tags. "Wide=yes", "smooth=yes",
"gentle=yes", "bumps_and_kerbs_and_stuff=yes", etc., are not
2) As I've said before, you gotta tag explicitly. Look at those
categories - what are the factors involved in categorisation?:

a) width
b) surface
c) corners
d) presence of barriers
e) the law

Funnily enough, all of this stuff can already be tagged explictly and
verifiably (see width=*, surface=*, barrier=*, etc.). Sure, you might
be able to save a couple of KB's in the database by using your
conglomerated, fuzzy categorisation scheme, but I think you'll find it
won't solve the current problem.
