You’re implying 98% of cars are going to occupy one lane and then 2% will use the passing lane and that’ll be just fine? That’s not very efficient.

Again, this is normal for the Autobahn. All the bad behaviors you see on US roads (left-lane hogging, passing on the right) will get you an expensive ticket there.
