How good are American roads?

I bet the proportion of unpaved roads would look a lot less bad if it was done by lane-miles rather than road-miles.

Of course, nearly all roads with >2 lanes in the US are paved. But that doesn't tell us anything other than the fact that we have the money to pave roads that are frequently traveled.

Truly, we have so many underutilized overly wide roads. Simply removing lanes makes money go much further
