You may be right about the reduced benefits of a 55 mph speed limit, although some fleets of trucks were very rigorous about enforcing it to save on fuel prices.

A couple of months ago I drove nonstop to the beach in my 2003 Camry 4-cylinder. I may have had a tailwind, but I covered 240 miles with exactly six gallons of gasoline in about three hours and 45 minutes, hitting 75 mph in some places. I am pretty sure that was an accurate measurement of gasoline consumption. I doubt that cutting the speed to 55 mph would have improved the mileage much over 40 mpg.

Just as a historical note, Ford was still president (until January, 1977) about three years after the 55 m.p.h. limit went into effect. Supposedly it was kept on for "safety" reasons long after energy supplies ceased to be an urgent issue. All it really did was to teach a whole generation of drivers contempt for traffic laws. Ever notice when people in a 60 or 65 m.p.h. zone see a radar unit, they still slow, not to the speed limit, but 55?
