TheNextMrsBuble - a whole different thread but at 79 your mother very possibly should not be driving anyway. OK she may be perfectly fit but what if she were not? Both my father and FIL at 70 should not be driving. You see the problem is that a lot of people have become dependent on a car because they live in a place that requires it or because they just refuse to use public transport so dont know how it works. Then they get old and their health fails and they are trapped. In fact the statistics showing how many old people are still driving is really shocking.
In my case and in DW's case we will never drive so we are already making proper plans about where we should live when we maybe are not quite so fit. For us, old age may bing many things but not isolation because we suddenly get ill and ca no longer drive.
For example, I was talking to a 65 yr old taxi driver a few weeks back. I told him I couldn't drive and he said the classic 'oh I couldn't do without a car'. Not in the sense he needed it for his job but just because he had always driven. It was part of his identity. He then shockingly told me he had had a serious heart operation 5 years earlier and had to stop driving for a whole 2 month period and he said it was 'hell'. He actually lived in a town right on a fantastic bus route and very close to an urban railway and easily callable taxis but described being not able to drive as a 'hell'.
While the OP has castigated women who don't drive - but what about the old women who have not only lost their husband but also suddenly too ill to drive and living miles away from amenities? Now that is isolation and dependency writ large.
Dont even get me started on the battles we have had getting my father and FIL to stop driving - they are just a risk on the road. My mother and MIL are both non drivers so depend on their husbands for transport - but only because they live in a place that demands it. They have never made plans for life without a car. Makes my blood boil.
Both my Great Uncles died in car crashes when elderly as they had heart attacks at the wheel and drove straight across duel carriage ways into oncoming traffic. The taxi driver who drove me yesterday age about 60 confessed he had difficulty seeing properly at night and drove really slowly looking at the nearside kerb when cars came towards him with headlights on as a result.
Yes old age happens but car dependency in old age is not a good thing and having a car can be a far far bigger trap than not having one.
