So the first indication that something is different was when I went out to my car this morning to go to work, and instead of the usual 41~42 mile range indicated, it says 37. And I'm thinking, did the charge get interrupted or something? But I can see no indication of that. So I drove on to work and it seemed like I arrived with about the same range left that I always do, 22~23 miles to get me home. It did seem like the accelerator pedal was a tad more responsive from a stop than it was, but it was already very good, especially compared to a gas car. I'll be watching how it goes on the way home.
UPDATE: Had 15 miles of range showing when I parked at the house.
