Didn't obstruct any traffic, and there was no danger of dipping any battery into danger voltage territory, but still earned a self-administered dope slap.

I'm sure the pack was very happy to slurp down some juice last night.

303 wh/mile for the excursion, which is pretty high given the low speed & "non-stop" nature of the drive. Batteries don't like the cold.

Plan is to keep the car licenced and insured for the winter, but only use it if the roads are dry to minimize salt damage to the body.

Would a few watts worth of heat (say 100 or so) be worthwhile along with some insulation to mitigate the cold losses?
