Well that's an interesting form of profound deafness...it gets worse when she's stressed. I'm not sure how you can have even less hearing when you are profoundly deaf...you're as deaf as you can be to start with.
There is also no need in this day and age to get lost like that, between google maps, sat nav and of course doing what people have always done, which is preparing ahead of time. sheesh I remember the days of getting the huge AA atlas out before going somewhere I didn't know and planning my route out before I left, and obviously you can't use a map of that size where your journey is spread between several pages, so I would jot down a few road numbers and general info on a piece of paper that I could glance at when driving..,A76, A75, M6, jct 17 A50... not bloody difficult even without today's tech.
And for the woman who never eats, why was it so important to get something before going home, even though she had an elderly collie with her and 3 others stuck at home. She just uses those dogs purely for show, oh look at me, I'm such a good person with my rescue collies and I feed them luxury human food, when in fact that is not good for them and she actually treats them appallingly.
And I cannot believe that they didn't check their phones or financial situation before making a trip like that, good grief I've got a 7 mile country road to drive to get to the nearest big town. I always make sure my phone is charged and has credit in it, and that I have my debit card that also has money in it and plenty of petrol to get to my destination. Even though it is a very short journey on a road I know very well, as I'm in my 50's with a few health problems, I would never leave anything to chance and end up potentially stranded.
