How good are American roads?

> Interestingly, in all cases urban roads are worse quality than rural roads, presumably because they see higher traffic than rural roads.

There's more infrastructure under urban roads. Crews come in to fix some utility, shred a section of a lane, patch it poorly with dissimilar materials, and leave.

Rural roads are often unpaved. The local authority has to come by regularly with a grade to redo things or they become unusable quickly. Overall this is by far the cheapest way to have a road, but it doesn't scale to high use and city folks demand something that makes less dust. Rural roads also includes minimum maintance roads which demand 4wd (real 4wd, many SUVs will have trouble) when the weather is nice and a winch is a must when things get rainy or snowy.

Though given his definition of quality I expect he is actually ignoring all the real rural roads and only talking about major roads which while they get less traffic than urban roads are maintained to similar standards.

Like the other replies have indicated, I'm not so sure this is the case? I live in very rural northwest Iowa, and while there are certainly plenty of gravel roads around here, I'm only driving on them if I'm intentionally trying to go "off the beaten path." You'll take a gravel road if you live on a farm, or you're trying to get to somewhere secluded such as a lake, campground or maybe a county park; but (imo) it's rare for the average person to drive down a gravel road just going from Point A to Point B on their daily commute.
