Actually, the morons who can't drive problem is easily rectified by raising the bar on getting a driver's licence. In Deutschland, where getting licences is a rigorous process, the problem is largely absent. Similar to awards and A's, driving has come to be seen as a right and not a privilege.
Drivers also appreciate driving more in Deutschland. They drive for driving's sake, while in the US, driving is just another waste of time, and people eat, apply makeup, make phone calls or text, etc. while they are driving.
Even if the US has the world's largest network of highways, you won't see anything like the Autobahn in a nation full of distracted drivers.
I think this is just a problem with larger metro areas.
Normally, at least once a week, I spend several hours on the road, because I enjoy driving. Sure I'm often going somewhere, but while I'm driving I'm sucking in the beautiful countryside, and will often take scenic routes because I enjoy taking it in. The first thing you have to do is get away from society and get off the highways.
