It's not like there are no laws on the Autobahn. There are some put in place to make things safer. First off, I believe they do need a special license to use it. Some sections do have speed limits that can change according to traffic conditions in the area. They also are not allowed to pass on the right, left lane passing only. But, American drivers are so used to the way things are now, it'd be hard for most people to break the habbit of driving like an asshole.
