For me, it's general laziness. I like to set the psi about 3 psi above the number on the door jamb to give me some latitude between tire pressure checks. I don't check my psi as often as I should, but tend to eyeball the tires and use the TPMS as a backup. I've never had the TPMS come on in normal operations except when I've had a puncture. And I've had several of those.
I don't know if the G2 RL uses the same criteria as the G! RL, but the G1 RL TPMS illumination range is ~24-29 psi:
