Bob's new video is about how to save money on fuel. He offers numerous ways to save.
However, at 7:50 he says to "turn off air conditioning". That is wrong (unless you are driving slowly Eg. in town). You get better gas mileage if you use air. Especially on highways. I learned that in the 70's from the Shell Answer Man. Anyone remember those commercials?
