My DH gave up driving in his mid 80s. He had a senior moment and took a wrong turn and the police car was right behind him. So, it was the police who revoked his driving licence.
We are lucky. The bus stop is just round the corner from our house, and it runs every ½ an hour to the town which is 15 minutes away.
I tend to walk to the local convenience stores, supermarket, hairdresser, dentist, surgery, Zumba classes.
If I cannot be bothered to walk, I call the taxi. The taxi fares are quite cheap compared to the city that my daughter lives in. My daughter lives roughly 35 minutes away by train.
My former colleagues live in the countryside. Once I had to call our local taxi to travel 11 miles to pick us up after 10pm. The bus does not run late at night there, no taxis either and signal was very bad at the restaurant. Absolute nightmare.
