It is good to relax, at least some of the time, about range anxiety. It is also important to "be very careful out there" when traveling outside your home area. We are in Kalispell at Glacier National Park, and took a trip up to Fernie, British Columbia today. I have and 85D with about 260 miles of range. I checked and found a free level 2 charger in Ferniie at the City Hall. I had a back up fast charger (CHAdeMO) on the way up and back, about ten/fifteen miles away from Fernie. Because I stayed under the speed limit, watched my usage, and loved looking at the mountains, we made it there using less than half of our energy. I would have liked to have charged at the City Hall Level 2, but a Volt was there. Another Volt owner stopped and was friendly and told me where I could find the Volt charging owner (just across the street, working) if I wanted to ask to use the charger. I decided not to because I had over half a charge and was going right back where I came from after lunch. I, again, drove in a leisurely fashion back, with 4% charge left. The car had said all along that we would have 5% left, and it was off by a couple blocks. I have learned to trust that percent figure, more so towards the end (because earlier on it is being conservative and working hard to make sure you don't run out). I did not like that I had yet to go five miles up the mountain to get to the B&B with low percentage left. But it work nearly perfectly. Had I charged during lunch, I would have had extra. Had I gone to the fast charger slightly off my path, I would have had extra energy. I had a backup also in mind, a destination charger at a hotel ten miles from home if I needed it, but I am experience driving my Model S and I trusted what it told me. So be careful out there (when in new areas, away from home and superchargers, in terrible weather) and watch out for the other guy.
