Had my first case of "Oh crap, I might actually run out of battery" tonight, but all turned out well. Had to make an unexpected ~55 mile trip and left with about 79 miles showing on the car. When I got to my destination and started heading back, the Navigation showed that I would make it back home with 3% battery left which left me pretty uneasy. I did the whole trip there and back basically following the exact posted speed limit (using TACC) and turned on Range Mode on the way back. I actually ended up gaining a bit more as it updated to 4% left and made it into the garage with 11 miles left. Right as I pulled into the garage, I got a warning regarding the battery and temperature - seems I barely made it, but did pretty well on the Consumption.
