Running the engine is a very inefficient way to heat the oil (sometimes requiring a plug-in _electric_ engine block heater if it's so cold the bearings and rings would be insufficiently lubricated to start), and doesn't work at all to warm up a gelled tank of diesel. It's ridiculously inefficient to try to cool the cabin.

EV heating and cooling is far superior to warming up a gas vehicle.
