Just a quick day trip to the White Mountains from Southern NH. Started out fully charged in a 75D from Hooksett for the 206 mile round trip back to the SC. On the return leg I put in my house as the destination and the car said drive under 55 and I would arrive at my house with 3% range. I ignored this advice (as I said I knew I was stopping on the way home for a quick charge) and drove the speed limit. The range went to below 0% and all it did was nag me to slow down. It never suggested a SC stop, even as I got to the exit it for the SC it didn't. How could it let me drive by the last SC before arriving home with an indication I would run out of energy?
