Reply to comment by Diligent_Nature 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

I was refering to the concept of "subzero", which is used a lot in metric countries, but I can't imagine it being that useful in you operate in F.

Wasn't refering to the relevance of 0°C to vehicles.

"Sub zero" is a reference in C. Just because you can aply to any referencial that goes bellow 0 it doesnt really matter.

But, we say "subfreezing." Your meteorologist likes to say sub zero in the US because he's a cool MK character. There's really no other reason.

I don't care what your car has inside it. 2/3rds of the rock it rolls on is water. Problems will arrise if you drop below the freezing point of water, for your car, your home, your health...
