I hope you're kidding.. but at the same time.. I was waiting for someone to ask this question..
In Alaska, and many other places it gets cold.. We have heating pads under the tranny, oil pan, battery, and somewhere else I think. And the engine block heater. Makes it a lot easier to start up in the cold (faster warmups) , a lot easier on your engine also. In Alaska, we can get down to -50, sometimes in rare occasions worse. Well maybe not rare.. haha.. But yea, it can get pretty cold.. our cars don't like it one bit.
For example, anything from 10 to -20.. If I don't have it plugged in (And by that, I mean have had it plugged in for the past 2-3 hours), my auto start refuses to start my truck up, and if it manages to.. it'll idle all over the place and die. (only happened once with the idle problem n dying) If I try and start it by the key, in temps of 10 to -35.. oh boy does it sound bad.. very slow start.. and it'll run 1500rpm until it can warm itself up. But haven't been in a situation yet where it refused to start up at all.
