Ah, I see.
Made up figures then with no facts.

No, not 'made up' figures. Just *my* personal experience in 37 years of
driving including road rallying (in the '60s and '70s with the RAF Motor
Sport Association), 7 1/2 ton trucks and small van deliveries (multi-drop
and long distance). When I've worked for companies with fleets of similar
vehicles I was always able to get better mpg than all the other drivers by
using some of the techniques employed by drivers in the old Mobil Economy
Run (does anyone know if the MER - or its equivalent - still takes
place?).

No science then.
Just figures that you think you remember.

What is the fuel consumption of a modern, standard CAR at 20, 30 and 40?

Do you have any idea.
