I don't mind driving 55 today, or any day, but now when I get on the "big road" I bump it up to 65-70!  As the speed limit is 75, and most people push that a tad, I just smile as they drive by, and say I'm glad I'm not buying thier fuel . . . 
Of course when I was on the Autobahn . . .my wife was screaming most of the time for me to slow down  (Well, it seemed like all the time!) |
My usual cruising speed in a good Mercedes is 80-100. Depending on cops, and the road of course.
Last year coming back from a GTG, I ran at 90-105+(most of the time over 100
) for an hour trying to keep up with an S600. Mileage for the diesel was still good even at triple digit speeds.
FYI the S600 got high teens, even though it saw very deep triple digits more than a few times on that run. I thought that was excellent mileage for a 6L V12, running at or near WOT.
