American here, I have a disabled family member. Cars are ultimately harder on them because they physically cannot lift themselves into a car while also stowing their 200lbs wheelchair.
A bus or train doesn’t have that problem and are therefore better.
And the more walk able the area the better because it makes it far easier. I’m sure there are disabled and elderly people who have an easier time using cars. But to say in a broad sweeping generalization that it’s better for all disabled and elderly people is a mistake. Cars should not be the first go to for a solution.
And kids can’t even use cars. They are dependent on public transportation and the walkability in their area.
