The smoothness proposal sucked - I got semi involved in the discussion,
but actually never voted either way - came in a bit late once the
barney was already in full swing (mostly trying to locate a nice way of
tagging 4WD only roads). And what fun it was....
There are a couple of proposals kicking around under fairly average
names that attempt the address the subjective issues raised in
smoothness, and to improve the surface type and surface condition
descriptions (as well as attempting to deal with this issue across
multiple transport types).
Parts of a proposal I made on the Smoothness talk page are incorprated
into the surface unification feature, some of which I think has
potential provided sufficient loving is given to the proposal.
