I was just about to cross a three mile bridge in the wife's 09 Corolla when
the TPMS light came on.
I stopped at the base of the bridge where there was still ample space to
pull over.  Found the right rear tire leaking bad enough to where I could
hear the air escaping over the traffic going by.
I wouldn't have made it across the bridge.
I always thought the TPMS was useless too until that experience.

I have wondered about the real utility of the TPMS.  I have it on one car
(not an option).  So far as I can tell, being one who checks tire pressure
regularly, and looks my tires over at every stop when traveling, it is of no
value.  I have a manual TPMS in the glove compartment, and it works
perfectly when I apply it.
