Good additions. I just took the model's output at face value and graphed it. Twould make sense that Rolling Resistance increases a little as more friction would indicate. Also interesting on the no wind resistance until 37 mph. I have often heard that 45 or so is the most efficient speed and the 37 would support that. But I know from riding my bike that wind resistance DOES increase from about 5 mph and up. By 20 MPH I can really feel it. (Empirical evidence).
Thanks for the corrections.

PS. I am getting grief from friends who drive a lot who say they'd go crazy driving any slower than 65 MPh. Think driving from Boston to Buffalo like that.
