After a year with the car I've gained enough driving experience to learn how to manage battery consumption on a long drive so that even minor range anxiety is gone. Today I drove about 210 miles with a start charge of 250. Ended up with about 15 miles of range left. I avoided my usual highly aggressive driving style, kept the speed under 70 (closer to an average of 55), and chose a route that took me off interstates onto two lane back country roads (with max 55 mph speed limits) that not only saved distance abut also range. And I arrived at my destination with time to spare. On such a long trip I do a standard overnight charge to full range. Then in the morning I switch to a Max Range charge about 75 minutes before my departure time. That way the battery is not at Max Range level for more than a few minutes.
