I'm not sure how the Tesla's are designed, but my Bolt doesn't loose energy like a normal car battery does in the cold, it burns the energy to keep the battery warmer, so it actually helps to heat the garage. It's designed to be plugged in and remote started in this weather. That helps preserve the battery because it preheats everything. I certainly understand the issue about needing a garage. We waited to make the jump until we were back in Wisconsin because our garage in the Twin Cities had no electric, so the charger install would have been very expensive. That said simple chargers with just a 220V hook-up are not very expensive at all, and if apartments with parking installed them it would be a huge boost to the accessibility.
