So I was frequenting fueleconomy.gov, and I went to the driving more efficiently section, (even though I've been there more than a dozen times) and I realized that they had changed their guidelines for driving speed. Before they said that every 5 MPH you drive over 60 is another $0.24 per gallon you pay, but they've changed it to 50! Check it out:

That to me is rather significant. Most highways in the US are 65, some ranging up to 80, but it used to be 55. I wonder if they are going to bring the speed limits back down to more fuel efficient speeds, and if they do, it'll be way easier to go 50-55 on the highway than it is now.
Any thoughts?
