On accuracy, I've always assumed the built in gauges to be crap so
marginally over inflate then check/adjust with a good hand held sliding
pressure gauge. The one I use is a low displacement one originally
intended for measuring air pressure in motorcycle forks and has a slim
plastic piston that has a better than average 2mm or so per psi
division.

Over inflation - although not dangerous - can lead to rapid wear in the
centre of modern low profile tyres.

Isn't it likely to affect the stability program on some cars, just when you
need it?
AIUI they know what will happen when they brake a wheel, its not going to
behave as expected if the tyre pressures are significantly out in either
direction.
My car will actually warn you if the tyre pressures are unsuitable (too low
or too high) for the load in the car, so someone thinks its important.
