The age old debate on if 55MPH is a good idea for the reasons suggested. Fuel savings and safer roads are the top given reasons.
The debate for it is defended using the issue of drag. The resistance of your car as it travels and the amount of it that is reduced thus saving fuel. I say HOG WASH! If you want to discuss drag, then we should also discuss inertia of motion. The more momentum your car has, the less fuel required to maintain that speed on an even surface. But saving that for another day.
Speed is not what burns fuel, its Revolutions of your engine measured in minutes (RPM) Today's cars are designed and transmissions geared to be turning about 1500 to 1700 RPMs at 65MPH. My Durango and the wife's Lexis at 55MPH has not gone into its tallest gear yet, and actually doing over 2000 RPMs at that speed. At 65MPH the overdrive gear had kicked in and we are back to well below 2000RPMs.
If we REALLY were trying to save fuel, then we would be mandating taller gears by American cars. We already have vehicles that actually drop half its cylinders on the freeway saving half the fuel it would burn.
Food for thought (made me laugh and think at the same time) Heard on the radio the comment, " I don't hear anyone demanding the airlines drop speeds of aircraft to only 300MPH." Hmmmmm... Maybe we should tax Water recreational craft and all terrain vehicles not used in a work capacity then.
