I like your basic thought process, but as shown by Germany the correct answer for straight, flat rural highways is to not have a speed limit at all. 120 MPH is

  120 MPH probably exceeds the the speed of reaction time for most drivers. A not-that-tightly packed group of cars going 120 MPH with a single blowout could have devastating effects. There simply isn't enough road to having a following distance big enough. Not to mention there would be entire classes of vehicles not able to safely travel (or travel at all) at such a speed such as semi-trucks.

    It is probably on the edge of too fast. That's why it's a speed LIMIT. We've grown accustomed to assuming that the speed limit the speed we should drive at, and going faster is no big deal. I think it contributes to a general disdain for rules. Setting it high enough that there should be no reasonable excuse to break it, should change this.

  Driving on four lane Autobahn can be very stressful, because you have trucks in the right lane going 80 kph (50mph) to save fuel, and the fast guys going 200kph+ (125mph) in the left lane. If you're going some reasonable speed like 130kph, you're endlessly passing the trucks, but you have to watch way back before you pull out for the car or motorcycle going 225. Although it's fun to go fast, I don't think it's a great idea to have more than a 2x difference between minimum and maximum speed on a road.
