It really isn't. (very) low tire pressure is a major safety risk. The TPMS sensors I've had all seem to go off at minor deviations (few psi) from the tire pressure; deviations that aren't a safety risk.
A useful reminder that the winter is coming, but hardly a major safety risk.
Close to 300 people died [1] in the 90s due to improperly inflated tires. Sorry, but I don't screw around with safety factors like this when I'm being hurled down freeway interchanges at 70 mph.

Uh no, according to your own source they died because of tread separation caused by a number of factors, one of which may have been underinflation. But in this example the 'underinflated' value was manufacturer recommended, so a TPMS wouldn't have helped anyways.
Ah sorry, that's the global statistic, not the US statistic.
Still, both statistics illustrate the point - 300 deaths a few decades ago involving faulty tires that may have been exacerbated by manufacturer-recommended underinflation have basically 0 bearing on the marginal risk of driving with a TPMS warning light illuminated.
