It's actually quite pleasant, and less white knuckle than driving 60mph in Washington State. The drivers in Seattle are ranked 181st out of 200 in US cities. In Germany, people drive much better (getting a license is much more intensive). Most importantly, people generally do not move to the left lane unless they are passing, and they don't attempt to pass if it would impede oncoming traffic. They are trained to look for torpedos. When I was in Germany, the car I rented on the way to the Nürburgring was capped at 140mph, which was quite frustrating. Once I got to the 'Ring, though, and rented my track car, I felt better. Anyway, on the unrestricted sections of German highways ("autobahn" just means highway in German), cruising at 150mph is pleasant and safe. They have far fewer fatal accidents in the areas without speed limits than we have with them. Montana is a good example. Before they introduced speed limits in the 90's, their fatalities were lower. They nearly doubled once speed limits were put in place. For safety, speed limits on highways are terrible. The only reason to have them is to increase city revenue. If you're curious why it's safer without a speed limit, the answer is simple. There is no road rage, and people check before changing lanes. Simple.
