Used to rent a car in Germany (they had the cheapest rates) and drove to East Europe every year. Now I have had enough of the driving, not to mention that the rental car topped out at 160km/h.
Don't believe those fools who claim that "everything passed them by at 180", bullcrap. Gas is very expensive in Europe, there are a lots frugal people there too with small cars/engines.
Lane discipline is awesome, but some of the bastards have no patience, especially young punks in 6cyl VWs. I had been "pushed" a few times because the idiot thought that it took me too long to pass the 18 wheeler (rental cars are rarely speed demons).
Of course as soon as I reached the semi's cab I matched its speed.
This happened mostly in East Europe and Austria though, not in Germany.
