I admit, my driving circumstances are ideal for optimizing mileage. I have back road farmland and highway segments to and from work. And you know Rt9 during rush hour averages about 40MPH so I overuse EV for that segment, then jump onto 18S to recharge and them some more EV on RT 34 past the military base. If you ever see someone driving slow and a bunch of angry commuters beeping, you will find me up ahead. No seriously, i do drive slower than the speed limit but i stay to the right. It would be interesting to have Gripper's vehicle here in NJ to test or us out there to test his situation. I tried to really get bad mileage a few tanks back, i was racing on the gsp and 18, went as low as 35mpg but i was able to nudge it back to 39-40 within about 100 miles. By the way, the member who posted in the mileage database for nah does not have a hybrid, the car info states it is a 1997 altima, way before it was available as a hybrid.
