I saw a show on the autobahn, I think it was Modern Marvels, and that dude that went 270. Thats wicked fast.
The autobahn actually has lower fatal crashes than US roads, mostly because the cars are built to crash on it, and they use double railing, refinish the road frequently, and drive totally differntly than here in the US of A.
Of course, I'm only taking this from the top of my head of what I could remember. I saw it like, 2-3 years ago.
