Just as an aside, I'm been very happy with the EV range estimate. (Obviously not with the HV range). Yesterday I took a fairly hilly round trip to the next town that is 25.5 miles away. Range said 52. I honestly thought I'd hit some HV for a few miles. I got back home with 5 miles left on EV. So the EV range was actually 5 under. Granted most of it was two-lane roads at about 45 MPH with a town on each end with some stop and go, so I wasn't doing 70+, but still happy since I have to go to that town fairly often.
(Of course I don't expect to make it in the Winter. Oh well....)
