Is it really, though? If the car isn't moving very fast, it's not using a lot of electricity. The amount of power it takes to heat the cabin is a tiny drop in the bucket compared to what it takes to propel the car down the road at a reasonable speed. If you're mostly idling/creeping forward I would think the wh/mi would actually be quite a bit less than if you were flooring it going ~80+mph at normal temps?
Sorry, just saw the notification that you had responded. Back in 2014/2015, my old Model S on the original interface showed a detailed amount of power draw. I was sitting at a red light when it was 0 degrees outside, and the cabin heat was using near 10kW. That's a lot of power. If you are stuck in traffic and barely moving, you could far exceed 1500 wH per mile. The slower you move, the higher that # will be.
