for those that travel between 60-75 mph, that's a huge drag factor
variance.  Mike's constant 63mph could easily get him over 20.  I
recently did a 270 mile round trip in our 142k Toyota corolla(99MY)
and it got 36 mph with me by myself in the car and maybe 150# of car
parts and tools along.  the same trip with two humans and more parts
netted 32+, with a slightly more leadfooted spouse driving some of
the time.  Wind wasn't a factor on either trip nor was ambient
temps.  FWIW, the car has no cruse so the driver had to maintain
whatever speed was to be had.
