I was thinking of software only solutions, but I think a hardware fix may be best.
I wonder if Tesla chose to optimize for other scenarios in the design of the car: Tesla distributes the battery across the entire body, which makes for great handling, fault tolerance, and safety, but may make it more difficult to insulate than in other cars, which typically just lump the battery in the back, surrounded by insulation.
An "inside" battery also takes advantage of the solar greenhouse effect from the glass-enclosed interior. On cold-but-sunny day, a parked car will heat up substantially simply due to the ~1kw/m^2 of solar energy delivered to the vehicle. Of course, you don't want the battery getting to hot, either. In addition to better thermal insulation, perhaps Tesla could add solar panels to the roof to aid in heating and cooling.
I hope this problem is solved, as it would be a bummer not to be able to take a Tesla on a ski trip.
