That's hogwash. I can pre-heat my Tesla from my iPhone, with it's heated seats and heating steering wheel, without risk of killing my family from carbon monoxide, all while it's plugged in and not drawing any power from the battery. Our family just took it on a 2000 mile road trip in sub 10 degree temps from the east coast to the midwest and back, and I have the one with the small battery, the Model X 75D. Yes the range is reduced 20-30% but it's completely predictable. An "auxiliary fossil fuel heating systems" sounds like a truly terrible idea.
