I had to convince my mother to stop driving 20 months ago. It then became my job to find people to drive her. I found that women who work as nannies often had free time during the day when children were in school. Not perfect coverage, so she has to take taxis at times, as accessing Uber would not be an option. I now have caregivers coming in a few days a week because I feel more comfortable having someone walk her from the front door to the car, since the taxi driver does not get out of the car.
It was not an easy discussion, but I tried the usual array of asking her how she would feel if she killed or maimed someone and also pointing out the annual savings by giving away the car.
I order her groceries and have them delivered weekly. The drug store will usually deliver prescriptions, and Amazon covers many other items.
Good luck…it’s a process.
