Woohoo, I did it. I got a 70+ mpg trip out of the Mirage. I probably annoyed a few other drivers. But, I really tried to stick to lower traffic roads and lower speed roads on the way home tonight. This probably isn't a doable every day thing, but I did do it!
For reference, this was on my 14 mile commute home. Ambient temp was around 80F. I kept the windows up and only used the fan. I got stuck by a train and got to open the windows for a little while, yay. But this was pushing it pretty hard hypermiling wise.
