Not all elderly people can afford them regularly. My mum doesn't drive very far but she does go out most days.
I’ve started to explore the possibility with my mum.
Cost is very important, especially to a person brought up during the war/postwar period with the lack of goods/make do & mend mindset (which is good, and certainly better than the throwaway society).
I think if anything goes majorly expensive wrong with the car, then that’ll be the point to switch over to taxi’s. Because at that point you can throw in the cost of repair/new car, let alone road tax, fuel, mot, (parking), insurance and servicing - with all the hassle and time that involves.
Lay it out like that, and then work out the average cost of a ‘day out’ in a taxi, times how many days in a year they go out.
Compared to picking up the phone and getting a taxi, I’d say the cost over a year (let alone the hassle of all the other bits you have to deal with on a car), will be far less for someone who just does local drives.
