Although, for big bulky Hank (1987 FJ60 Land Cruiser), there is a huge difference in mpg between say, 50, and 70. Drops like a stone.
Yeah, less aerodynamic vehicles would see a sharp decrease in mileage at higher speeds. The same is true of vehicles without overdrive.
I thought that was a myth! Or at least I didn't think there was an appreciable difference between 55 and 60.
I think it would depend a lot on aerodynamics and maybe gearing.

No, I couldn't do that so one of the guys could have been who you mentioned but I don't necessarily recall him.
