On the opposite side of the coin, in So. Calif it will occasionally get above 90F and my iPad Mini2 will overheat if I fly outside. So I will fly from inside the car with the air running. As long as I'm diligent about keeping the craft in front of the car with LOS through the windshield, I'm good. I've got over 1mi range from flying inside the car (P4P or P3P, FCC mode with windsurfer).I live in northern Minnesota, where winters are less than hospitable. I was dieing to fly my new P3SE, so I took it to the park and flew till my fingers were numb, landed the drone and sat in the car to warm up my hands. My wife said "why don't you just fly it from inside the car", which was an extremely appealing idea. As soon as my fingers thawed, I tried it and it worked great. I only flew it out in front of the car where I had clear line of sight. I was able to practice POI and waypoint missions without freezing my digits.
Other times I'll fly from the car just to get shade if no trees are around. It's can be more comfortable from the car. If I'm not on a 2+mile mission, flying from the car is viable. It's also a great way to keep people from seeing me fly, potentially complaining or making trouble by calling a LEO, even though I'm legally flying. Flying stealth helps prevent hassles.
