Boredom? No WAY! A long drive on a sunny day with almost no traffic? That's relaxation time to me! I hardly EVER get to drive on a freeway with no bumper to bumper action!
I think some of you guys are missing the point. I'm not going to start driving 60 mph all the time. In and around Seattle I'd end up with some rice rocket stuffed in my trunk sooner or later. Not to mention all the hacked off drivers making hand gestures at me one after another.
No, the real point is that, as much as we hated it, the old 55 mph speed limit that was in effect when these cars were new really did save fuel. As others have said, wind resistance rises exponentially as speed increases. Just slowing from 70 to 60 - a 14% decrease in speed - improved mileage by 7+ mpg - over 25%.
At present, there is somewhat of a growing movement to bring back the 55 mph limit. Frankly, I'm not so sure that would be all bad.
