One possibility: German drivers generally don't dart in and out of traffic because the slower drivers stay to the right, instead of cruising along in the passing lane.
Yep - it's the slow drivers hogging up the fast lanes that cause the trouble. That and big rigs who do the same.
How about tripling the fine for left-lane hoggers?

Passing on the right on the Autobahn can result in a 4 month (minimum) license suspension and a heavy fine.
