The woman in question lived in Merseyside. She is entitled to free bus and train travel in the region. There are public transport stops all over the place and everything has level boarding. Why would she need ferrying anywhere?
As it happens, I won't be ferrying anyone. I don't use a car myself any more (because the things are bad for the environment, bad for society, and bad for my bank balance) and my parents have started their retirement by moving to a bungalow 300m from a railway station and a bus stop, 600m from a doctor, and 800m from a Co-Op.
Not an option for everyone, granted, but my grandparents (who retired to rural Ireland) used to have a weekly taxi trip so there are alternatives. Driving when you're no longer competent should never be an option, no matter how inconvenient it may be to stop. There are lives at stake, and this is hardly an isolated case. I reserve the same scorn for the use of the "hardship" excuse to get out of losing one's licence when someone has been caught speeding enough times to rack up 12 points or more.
