Gasolina rant

May I take this moment to point out that cars run most efficiently between 55-60 mph. "The EPA offers this rule of thumb: Assume that for every 5 mph you drive over 60 mph, you might as well be paying an additional 20 cents per gallon for gas." Why in an era of Inconvenient Truth is no one talking about this?

Abby made fun of me for writing my senators about lowering the speed limit two years ago. She said it so off-the-radar they'd have just laughed shook their heads.

Here is a portion of the response from Senator Enzi('s office):

I agree that driving at elevated speeds burns more gasoline than driving at lower speeds. However, I am not sure that reinstating a NMSL at 55 or 60 mph is the best way to achieve fuel conservation. For instance, cars with their windows down are less fuel efficient than cars that have the windows rolled up because they have more drag. Should the federal government mandate that people drive with their windows up?

Heck, why mandate speed limits at all?
