I don't consider myself oblivious, and it really scared me how little the handling changed with a flat rear tire. It also didn't make any extra noise.
I have always wondered if it is the lack of sidewall on a 225/45R17.
I did notice in time though, somehow. The tire shop also couldn't find a reason for the flat, so they simply remounted it, filled it, and sent me on my way.

I've had a valve core get stuck open in a way that was released by poking at it. And the little plastic cap is amazingly good at holding the tire pressure in too. Sometimes rebooting the computer is the right fix.
