Today, I stumbled upon this video. It shows cars that remain running around the clock due to the cold, so they don't freeze and can start. The person in the video talks about how this prevents engine damage.
I rarely deal with such temperatures, so this seems somewhat strange to me. Being environmentally conscious is so important here that cars with start-stop systems have become standard. The goal is to minimize consumption as much as possible. Not to mention electric cars which, when charged "cleanly" (e.g., through one's own photovoltaic system), emit very little CO2. I'll leave out the topic of "White Gold" aka lithium for now.
