The cost of idling the car

"... In fact, one of the most powerful arguments in favour of reduced idling is an economic one.
For the average vehicle with a 3-litre engine, every 10 minutes of idling costs 300 millilitres
(over 1 cup) in wasted fuel – and one half of a litre (over 2 cups) if your vehicle has a 5-litre
engine. Unnecessary idling wastes fuel – and wasted fuel is wasted money...."

My Mitsubishi Outlander has a 3l V6 engine which requires high-octane fuel. So at 1.60/litre (more or less), 10 minutes of idling costs about 50 cents, or approximately a nickel a minute.

Or $3.00 per hour.

H'mm.

Footnote: On hot days, at our local mall parking lot, I often see people sitting in their cars with the windows rolled up, the engine and air-conditioing running. Even on days when a nice breeze blowing through open windows would keep the car cool. I think this indicates that fuel s too cheap.
