Absolutely. I was stationed in Germany for 3 years while I was in the Army. You could be in the left lane of the Autobahn, doing 90+ passing a truck, and suddenly a Ferrari that wasn't there 5 seconds ago is right behind you, flashing its headlights demanding you get out of the way (apparently you're supposed to merge into the side of a semi).
When I'm driving trough Germany I always encounter at least one worker van going the speed of light and flashing the <insert sport car> for going to slow.
