Watch on the autobahn in particular when it goes from no limit to a posted speed limit. I was riding over there (motorcycle) two months ago and I certainly took notice of going from doing 170+ km/hr to 80 km/hr pretty quickly.
I'm sure Germany has it's bad drivers but most, at least on the autobahn, are familiar with moving right after passing.
Ausfahrt means exit, not a rest area
LOL
