This is banned in my city specifically because idling cars produce a ton of localized pollution. I can go some places in the summer and basically get sick walking through a parking lot because it is filled with idling cars and I have (fairly mild) asthma. Please do not idle your car for only the purpose of maintaining temperature .
The part which seems under reported is that for a long time USCIS basically had an amnesty policy for expired visas while the next one was pending. I’d wager a very large percentage of people in the US who went from student/work visa to marriage residency technically overstayed their visa while the paperwork was being processed. There is no law which allows or otherwise protects this “paperwork amnesty,” even though it has been long standing administrative policy. This administration could therefore go after anyone who was naturalized in this way. And for no reason other than they think this is red meat for their base who just really hates all immigrants for some reason.
