Sounds good! Check out this link for info on the smoothness attribute: https://wiki.openstreetmap.org/wiki/Key:smoothness

In Thailand, dirt roads that city cars can't handle usually start at smoothness=very_bad, meaning small ruts that a pickup truck can handle. Bigger ruts or roots needing a heavy-duty 4WD are smoothness=horrible. If the ruts are so big only off-road motorcycles can get through, that's smoothness=very_horrible.

Hope this helps, and thanks again for your awesome contributions!
