The idea of "attended and unattended" has no relevance to the UK law I mentioned.
Irrespective of the prosecution rate Section 42 of The Road Traffic Act 1988 states it is an offence to have the engine idling unnecessarily when the vehicle is stationary.
There seem to be varying "official" opinions of what this means which could be why the law is not widely enforced - idling sitting in traffic seems to be acceptable but are you considered to be in traffic if stopped at the head of a que at a red light?
What you do on private property, such as a parking lot, is not covered by traffic laws.
Tin hat on, ready.
