(No?) Fun, Fun, Fun on the Autobahn

I've been to Germany a few times, and spent a month there last year working on an art project with Vera Lutter (She has a show up now at Gagosian, so go see it!). I understand the basis for the reasonings on an Autobahn speed limit - but I have to say as a certified car nut, that there is nothing better than driving on the Autobahn. The free-for-all-whatever-lane-at-whatever-speed meanderings of the drivers on the NJ Turnpike are gone...and replaced with a finely tuned set of "rules of the road". Above all, stay out of the left lane, and if you dare venture into it, watch out for the Mercedes/Audi/BMW/Porsche closing at 140+ Miles per hour. I managed 155mph flat out in a rented C-Class on the first trip, and barely 70mph in the Ford Ka work car last time (A little scary at times, that thing was a dogg). Even at normal speeds the German highways work so well they should be preserved as they are, and as most unique things are, cherished. A modern wonder of the world, if you will.
