"It would be like that totally pointless "MPG on the EU cycle" figure that car manufacturers have to publish, even though it bears no relation to real-life usage."
It doesn't matter that it bears no relation to real-life usage. What it does do is provide a comparison between two different makes/models, using one standardised baseline, so comparisons can be made.
Just like NCAP stars, 0-60 times, etc. they're just numbers to compare one to another to see which is "best".
