is the theory correct, thats its much warmer under deep snow?

Yes. A layer of snow is a very good insulator, because there's a lot of
air trapped in it.

It would still be damned cold though. Esquimo used layers of deer hide
as carpeting in a dome shaped hut lit and heated by lanterns burning
animal fat until Hugo Chavez sent them oil supplies to make up for
what BP took away.

I have heard snow is transparent to UV light but the car would radiate
heat into snow on contact. As would any condensate. Eating snow will
lower your temperature, you might drink the melt-water.

from Poundstretcher. Who knows what he was prepared for?
