This spectacular failure that has me ashamed of my roots (300 people stuck on a highway overnight in the middle of a city in a blizzard) has me asking: - How long can one stay warm in a Tesla stuck in a snowbank? Folks had to be rescued as they ran out of fuel to stay warm. Could a Tesla outlast this scenario? A few variables: Number of people Available clothing and blankets Number of seat warmers (winter package adds rear seat warmers in S) Outside temperature Wind Sun Now we'll assume proper hydration and food, helping everyone regulate their body temperature. What do we know? The figures here look promising. Although it is not tested in actual cold weather (have not watched video yet).
