Well wouldn't better driver's ed solve most of those issues? A tiered license system seems like an overly complex solution. I've driven in both Germany and the US (DC area, while on holiday), and found US driving a lot more relaxed. There are some odd rules here and there, but in general it was less unpleasant. Driving on the Autobahn can be quite stressful when you have a few people who want to drive really fast. Those kinds of speed differences reduce road capacity significantly. I'm not saying these people are necessarily unqualified to drive at such speeds, they may be the best drivers in the world, but everyone would reach their destination sooner if those folks were to stick to 130-140km/h. That said, the posted speed limits in the US are definitely on the low side. The same roads would have a higher speed limit in Germany.
