Yep where its so cold, block heaters are popular. You see little plugs sticking out from under the bonnet. Diesels are also less popular in frigid climates because the fuel becomes a gel at those temperatures.

With most BEVs nowadays, you can set the battery to warm up and also warm up the interior on mains power before you set off. Far more convenient and comfortable than scraping the frost off, getting into a freezing cold car, and hoping the engine gets warm enough to put out some warm air before you succumb to frostbite.

I've noticed that HN and Reddit tends to gravitate to ridiculous examples to show how "Solution A" can't possibly work.
