You know honestly this wouldn’t be a bad thing to do again with the fuel prices the way they are. I haven’t been driving a lot slower on the interstates anymore and keeping my speed down by at at least 5mph. I did some experimenting here a few weeks ago taking some back roads only doing 55mph-65mph and I couldn’t believe the difference in fuel economy. It really makes you wonder if it was a ploy to raise the speed limits just so oil companies could make more money.
