Well it's nice not to have a speed limit, but every time I see one, it's such a sigh of relief.
Story time:
Not so long ago, I was on that 4 or 5 lane autobahn before arriving to Munich. I was already dark, overtaking some car, leaving the most left line empty. Then these laser high beams basically illuminating the nearby Alps. I was thinking geez I'm doing 160, relax dude, you have a free lane here. I moved to the right, 2 lanes to my left are now free. Car flies by me, doing probably like 50-70 more than I, AND, AND this guy gets overtaken by another one with about the same speed difference relative to the guy doing 210-230.
