WOW! I would not have expected that be the car used on the "Highway of Bones" with insane levels of cold! I hope they were running it with chains at a minimum.
If you dress right, have a good thermal sleeping bag, have calories in your system, you can do pretty well. A fair number of sleeping bags have survival temps as low as negative -40. I've done OK once or twice at surprising levels of cold (sleeping in the back of car / SUV on a ski trip other winter trek is not end of world, even without cars heater).
Not totally clear still why this is a story about google.
