You're really not going to like driving in Germany, then.

Seriously though - the Germans are amazingly good drivers (easily the best in the world), and it's mostly because their training is so thorough. This results in their having a common driving culture, so that going 300 km/hr on their remaining unrestricted/uncongested Autobahn is quite safe.
