That's absolutely true. I always park facing my flight path and it is limiting in that sense. There have been some places I've wanted to fly where that was impossible and that is kind of the end of that if we are only prepared to fly from inside the car but we dress warmly and if need be standing outside for a few min is no big deal. If you live in these parts (I've had -75F at my house...) and let cold temps stop you from enjoying life.... In practical terms, meaning battery life and being able to stand/sit around outside, -30 is probably the limit for me with -20F about all I typically am willing to fly at. We also bring chairs and wear snowmachine bibs and winter jackets and sometimes just sit outside in a chair when it's ... chilly... Adapt or Die
...or at least...Adapt or sit at home on some forum thinking about flying....The biggest issue is control with gloves and cold hands.
