Assumes a fact not in evidence.

Drivers/riders can become "obsessed" with all this new info that is constantly updating. Alarms for "low" pressure exist also.
While a periodic check might be good, having it displayed all the time can take your concentration away from job #1.

If you really want to blow his mind, explain to him the coefficient of expansion and how the actual metal parts expand and contract with temperature changes. That'll really freak him out.

But if you have the pressures in a rear tire going up more than they should I would look at rear wheel alignment. If the wheel isn't tracking properly you are creating additional friction which in turn translates into additional heat causing the pressure to go up higher than they would normally. Also misalignment causes excelerated tire wear.

How do you figure? Yes in a car if the two wheels on one axle are not in alignment. However on a bike if the rear wheel is out of alignment then the front will be turned to compensate resulting in both wheels running in parallel and thus no additional friction.

Actually that is the max tire pressure COLD. Pressure can still exceed that while riding
