I would like to see a space where you can input your MFD MPG average and figure my MPG based on manual calculation and compare the two.
Als as I've mentioned before, more choices for percent of traffic and highway.
I also thought it would be cool to compare my Prius to my old car a Nissan Quest, which averaged 18 MPG. So if I drove the same # of miles how much more gas would I have used in my Quest.
