Hi Future Insight:
___The CVT based Insight can be forced into possibly a 85 - 100 mpg short length commutes even from dead cold with the right techniques, setup, proper in town traffic and roadways, and even alternate in city routes but as soon as you get into an inch ahead, stop, inch ahead, stop, repeat, your FE will tank. You would have to change your driving techniques drastically and to the extreme (I am really talking extreme) to receive that kind of FE but it can be done if you are willing to go through the motions from the instant you place her into N in your drive to the instant you turn off the key before arriving at work. It will be a ton of work but it is doable depending on how bad you want it. If it were me, I would consider instead a new or used Civic, Corolla, Echo, Ranger P/U, or Focus (must have a stick) to receive maybe 2/3 of the Insight’s FE over that same short distance from cold doing the same. Your TCO (Total Cost of Ownership) would be much lower w/ a non-hybrid in most cases if you are only driving 8 miles RT a day or less.
___Good Luck
