My only experience on the autobahn was this fall, and I thought it was pretty good (FYI, top speed of a Ford Focus is 190kph) with the exception of one jack*ss who swerved into (our) centre lane as he passed us at about 50kph faster than our 180 or so, just to shake us up.

Now if you want to live on the edge, hire a driver in Morocco. I think one of Mrs. AC110's fingernails is still in the seatback.
