Reply to comment by Kenbishi in 30 minutes of car preheating in sub-zero conditions produces as much particulate emissions as driving 97km in a gasoline car, or 20km in a diesel car “These findings do not suggest to stop preheating cars; instead, we could reduce the emissions by using similar methods that are in place for engine” by giuliomagnifico

Oh wow. Yeah I know what you mean about the temperature causing school closures, it’s common now but it didn’t used to be a thing. That’s crazy though! Especially if people had had to go outside after those accidents. -70F puts you at extreme danger of frostbite within minutes (although perhaps less so if zero wind? Not sure, just my guess).
