What's confusing about the AB? Drive to the right unless you're actively passing someone, pay attention to road signs to know if you're in an unrestricted zone and always watch your mirrors for faster traffic coming up behind you. If only American drivers could handle such complex stuff.LOL, but the Autobahn in Germany where you can drive practically unlimited speed is not a confusing thing? Come on! Every nation has "confusing rules", quite singling out the US.
Funny aside, it's illegal to pass on the right on the AB, and the one time I sat behind a car in the left lane that wouldn't get over, I finally went around them to the right, after checking for any popo in my mirrors, and when I went around, I looked over at the driver, and it was, you guessed it, an American officer with his hat on.
