I remember visiting an uncle in Calgary once and seeing the cars with block heaters and connectors so you could plug them in to keep them warm.
I think driving a car out in in -30 air would be fine if the engine is warm. Colder, denser air so it probably goes better. But the amount of damage being done if the car itself was at that temp and you tried to start it must be bad. What happens to the clearance in an engine that cold? Does everything tighten up? Combine that with thick oil and you'll get more metal to metal contact and wear.
