The article is not about pre-heating the car with its own engine before starting driving. That is allowed for two minutes in Finland, likely based on some EU regulation. The article is about small aftermarket heaters that use gasoline or diesel to heat an engine like an electric block heater heats the engine. Those are well abundant in the Nordics especially in diesel-fueled vehicles.
