again:

If the car has sat nav installed and available to the car's computer, as
many do now, the speed across the ground could be compared to the wheel
rotation. That could detect all 4 wheels being equally underinflated.

Maybe. gps speed isnt that accurate in the short distances.

And if you get 4 new tyres at a time, as many do, and the tyre place
underinflates all of them by the same amount, and the tyres are a
bit different profile wise to the previous set, its going to be hard
for the system to work out that they are all underinflated. And that¢s
the main situation where all 4 would be equally under inflated.

Darn, Mr Know-it-all has it all worked out, yet again! LOL
