what’s the penalty for idling?
Death by firing squad.
Confiscation of vehicle and loss of firearm privileges..
One month diet of vegetable soup . . . only.
IMO, in some parts of Europe it is a petty crime, but they have advanced digital block and interior heaters using car’s own fuel in less volume priced at about $1,500 as an option by most dealers.

For example transmission is very vulnerable. Using conventional fluids and no idling in Alaska or Siberia in winter is a proper way to ruin it in a month.
