These examples are exactly why I drive my other vehicles (wife's car, daughter's car, dad's car, etc) when I get a chance. My son would recognize something "wrong" and deal with it immediately; not so much the others in my family ... So I have to be "hands on" and drive them so I can get a perception of what's "normal" or not. If I don't drive them regularly, I end up with something like what happened to the OP.
Many years ago my aunt and uncle (now both deceased) had a brand new Chev Lumina. It died on her one day right in the middle of an intersection. Turns out it had no oil. From the day it was new, never got an oil change or any top off. It was my aunt's car to drive. A bit of contention in the household for a while ...
He: Didn't you see the little red light was on?
She: I don't do vehicles; it's your job to take care of it.
He just presumed she'd let him know about the "problems"; but she had zero sense of mechanical things. And I mean NONE. He wasn't a savant with mechanical stuff either; cut the tip of his finger off in a snow-blower by trying to clear the chute with the machine still running.
Two peas in a pod. Great people; loved them dearly. But no sense of the mechanical world around them. Zero. Zip. Nada.
To think that either of them would wait for the car to tell them something is wrong (like no oil pressure) is the indication that neither of them really paid any attention to the routine things like fluids checks, etc. Oil changes were just incidental to them both.
The only thing I would mention to the OP is that it's not just limited to females. Some folks just don't "get it".
