Reply to comment by tmwagner77 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

Was gonna say, but I also live in a weird part of the country (4-5hrs from the four corners). Today it was 12°F when I woke up, and in January it is rare for me to start the car when it’s over -10°F. My car is very heat efficient so it takes longer but 10mins is fine, my shifter will wake up soon enough.
