Perhaps we could adopt a new "surface" tag based on ASCII art.

A motorway might be
    surface=_________________

whereas a road "maintained" by Oxfordshire County Council would be
    surface=____.____ ____.__

a mountain bike trail might be
    surface=__/\__*__-_-_..._

and a horse race with hurdles would be
    surface=___|____|____|___
