I'm in the no EV in my future group also. Only way I would consider an EV would be as a 2nd or 3rd vehicle that was only for local use. To get back to the heater discussion, I commented to a friend up North that has a hybrid that getting stuck in the snow on an interstate like has happened a few times would not be good in a full electric. He had an answer, he said that a solar blanket to cover up with and a heated seat would keep you warm for many days in an EV. I have carried a couple of solar blankets in all our cars for years but never thought about that even in a gas powered vehicle if you have heated seats it would be a good way to keep warm, then you would only have to run the engine every few hours to top off the battery.
