I have an older retired mother who uses a cane and can easily move about once she gets into the store by using the cart to stabilize herself. Taking public transportation is a no-go where she lives, because the one thing that I haven’t seen mentioned here yet, is crime. As an older woman with a walking aid, she’s the prime target for criminals, who also know old and elderly tend to not trust banks and use cash.
I do what I can to help and support her, however this is not always feasible, and in her words, she’d “be damned if she wasn’t able to get out of the house and do her damn shopping herself”.
And she’s able to drive just fine. But I guess she should give up her car, her freedom, so you can feel better about, whatever the fuck you think it is that getting rid of cars will fix.
