This is one of the things I've wondered about: how do folks in AK, MN etc. cope with extreme cold?
The lower parts of MI don't really see subzero temperatures too regularly, but they do happen, and in the colder winters, have gotten down to -10f to -20f temps (not counting windchill. -22f is the coldest I've personally ever been in, and -60f windchill SUCKS. My uncovered face cramped up in under 30 seconds).
A few years back when we had quite a number of days where the temperatures were below -10f, I discovered that my older Yukon hated anything from -12f or colder. The keyfob wouldn't unlock all the doors. The starter would turn noticeably more sluggish, and even when the engine would start, half the gauges wouldn't work until the interior temps had warmed up a little.
How do folks deal with -40f and colder temps? I've heard of engine block heaters that can be plugged in etc., but what happens when folks drive to work and their vehicle is sitting outside in the parking lot in -40f for 8 hours or more?
