Richard, I would somewhat caution against penalizing unpaved roads too
much. In many areas of the US they actually make wonderful cycling routes,
whereas the paved alternatives are high traffic and unpleasant to ride on.
Of course, proper smoothness tagging would help but that will be a long way
coming. Until then you could consider a user setting to avoid/not avoid
unpaved roads.
