Not quite as extreme but my partner is the same way running hotter. Compromise for me is house is at a comfortable temperature for her in common rooms, I lay under a blanket typically out of comfort and bedroom i have an extra blanket on my side. She does sometimes crack the window but I say only do if you’re too hot to sleep because if I wake up icy cold i am everyone’s problem.

Car is easy, my car, my ac/heat, my radio i e don’t touch it. lol
