Of course the majority don't pay for the fuel used. But I still don't
understand why you'd want a noisy diesel idling while you eat your lunch.

so you can have the radio on ?


That’s what the “accessory” position on your ignition switch is for.

On our Vauxhalls, the radio stays on if you turn off the ignition but
don't take the key out.

If you do take the key out (and / or leave someone in the car without
the keys), they can still turn the radio on.
