The thing is.....I might be just the same when I get to her age and I hope I will be sensible enough to know when to stop driving.

My mum is night blind and stopped driving in the evenings quite some years ago. Now however she also has problems with bright light. She can't drive on a bright sunny day. So what is left in the end. She has to see if the light outside is ok for her eyes before she can hop in her car. Not very handy if you have to get to an appointment.

She had a frozen shoulder a few years back so couldn't drive for ages, then she broke her ankle, again didn't drive for ages, her eyesight got worse over the last few years and it's something that can't be sorted with glasses or an operation, so with all that you would think she would have given it up already. Her car is 17 years old (bought from new) and has about 10.000 miles on the clock. So it's not that she was ever driving a lot anyway.

It sounds horrible but I hope she fails the test.
