I'm guessing that you haven't gotten the April firmware upgrade, right? I think ten miles per bar is really high with that change. ... But then maybe you do have it, and are just a much better EV driver than I am.
You are right, I haven't gotten the firmware upgrade yet, but I have stopped looking at the range meter, so not using that as a base. I can guess pretty well at this point how much energy I am using, where I can gain some, and how far it is going to take me. I enjoy gaining charge so I do take it easy about half the time, but I am never seen as slow. I have never pushed the limits of the charge (Have only charged to 100% once or twice, never been into the bottom red), but with a 30 mile commute RT for a couple months I have noticed that I get a rough ten miles per bar. Made the 30 mile round trip to Burbank twice in one day, which made the wife a little nervous but I had confidence, even though the second trip was to the Castaway in Burbank. I actually want to put a smiley face sticker over that darn range meter number - it just bugs me and is useless, don't think any fix will help either. Elevation is the factor to consider most, and enjoy the ride, don't just want the ride to be over as fast as possible - you are not in an ICE any more, so punch it and regenerate as much of it back as you can.
