Reply to comment by Etiennera 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

That is…literally true, but it’s practically not an issue for most people with well-maintained vehicles.

I’ve started every vehicle I’ve ever had, one with over 200k miles it (with a good battery),in sub-zero Fahrenheit at least once without issue. The oldest was a Subaru with the short piston skirt design, so it made an awful lot of noise, but there was never an issue actually starting.
