Well, uh, coppercone2 your analysis reminds me of one response I had (or non-response): when older car (engine) threw a rod, partially thru the block:
DROVE that noisey / smokey old car, maybe another 15 miles, ignoring my ears. Acted like was normal, while 'just get me home'. But that thrown-rod engine didn't get better (go figure), instead the dash temperature gauge soared to max. Maybe no oil by then, but hey; still 'driveable'...
I's goin down, but didn't want that, so...kept driving, at traffic speed. Denial can be a powerful trait, get you through some, seemingly, bad consequences, just keep pushing the gas pedal....
Tow truck, later, dropped off the car, and myself, at nearby service station.
