I went from around 36mpg to 42mpg on my commute by driving the terrain. But something happened today I didn't expect. My Altima can go up to 43mph on battery alone, and today I was in a line of traffic for miles that stayed under my optimum speed. I was also at a section of road that was relatively flat. Well, I ran my battery down to nothing, or at least to a point where the ice had to run. There I was at a stop light and the ice was running! Arrrggg, ruined the entire commute (WRT mileage gains).

It gets late early out there. - Yogi
