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.
