I'm from the US--from Texas, specifically--and we have about four billion miles (you could drive to the sun and back more than forty times and never touch the same road twice; I'm sure that's not any kind of exaggeration) of dirt roads, or roads that used to be paved, or roads that are improved only in that they are clad with a layer of what we refer to as "caliche" (pronounced "k'lee-chee" around here). And then there are about four billion more miles of blacktop ribbon road so thin and pliant you could tie it in your hair. I'm not under the illusion that every place faces these same challenges in transportation, so I wanted to ask: how common are unimproved roads in France? The CIA factbook seems to imply they have none at all. I'm not sure what that's counting as "roads," though.
