My eyesight is borderline, I can read the numberplate at the required distance just about on a good day when the conditions are exactly right, but not some days, so I could probably scrape through my driving test, but if I ever caused an accident etc then I would not get over the guilt, because I know I am borderline. So its not exactly for medidal reasons but it sort of is.
What never fails to astound me is how many drivers think its okay to comment negatively on my lack of ability to drive (and no not people who have given me a lift), and who suggest I memorise numberplates before a driving test to cheat at the test because to them it is more important that I learn to drive than that I am legal to drive.
And yes my spouse does the shopping because he drives, but then if he didnt want to do it I would just get it delivered,I dont 'make' him do it. He had to do shopping before we got together, so why should he stop just because he has a wife...
I have public transport, shops and schools all within walking distance, because I chose this because I cant drive. In the same way a driver might choose a house with off road parking, or a garage. This shouldnt be hard to understand
