Heck, I do those sorts of "experimental runs" any time traffic and weather allows and I'm feeling rambunctious. I'm on the autobahn usually a couple of times a week, and about once a month I do a 150+km run down to the in-laws & extended family. That's when I go through a couple of unlimited speed stretches

That "legal top speed" you're talking about is basically as fast as you and your car can handle, assuming you are in an unlimited speed zone of course. Otherwise it really is important that speed limits be observed here in Germany, since they are pretty quick in taking away drivers licenses.

So... you coming over?
