Reply to comment by Broad-Kangaroo-2267 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

True. Definitely a consideration I wasn’t thinking about. In my climate it’s usually very dry during very cold days, so fog isn’t an issue. Even on moister, warmer days the defrost setting will still pump out dry air and keep the windshield clear. It’s COLD, dry air, but the cold doesn’t bother me.

You’re right, though. If I turn on the defroster setting and the windshield doesn’t clear up I’m forced to wait.
