What I'm saying though is I've driven 65 and gotten worse mileage. That's why I decided to speed up and I ended up getting better (??) going slower is fine, but I just end up getting everyone mad at me, especially on the two lane highway I drive. I don't mind driving slower and I do so when I can afford the time. My point in starting this thread was to see if there was somehow a speed that would magically help everyone increase mileage, apparently not, though. I'm not getting hostile or anything, it just seems like you're throwing out programs and stuff that simulate this and that when I'm telling you I've actually bettered my mileage with increased speed.
