>* Unpaved roads are difficult to really classify the surface in terms of
anything other than dirt/sand/rock. The surface state changes over time
from smooth immediately after grading, to possibly deep

opinion would be to use some sort of tag like surface condition (options
being something like: maintained | uneven | degraded |
>corrugated | rocky | rutted | deep_rutted, but even those change
immediately after track maintenance), with perhaps a best/worst case tag or

One thought that occurs here would be to tag the *maintenance* of a track
rather than its *current state*. Some tracks are essentially never
maintained, while others are graded frequently. That, combined with the
season that you're travelling (eg, late summer vs early spring) might be
enough to make an informed decision.

AFAIK the major issue with rendering changes is resources to implement
them. So, if someone writes the code to do it, much greater chance of it
