Is car culture good for disabled people?

Out of frustration with pandemic restriction arguments on Twitter, I made a comment saying, why don't we just ban cars instead of all these daft rules? And immediately got several replies of, but that's ableist! Obviously banning cars completely from one day to the next is not in any serious sense feasible. Fine. But it's exactly the same knee-jerk response you see, sincerely, anytime anyone makes a suggestion for any planning policy which makes things even the tiniest bit worse for drivers: what about disabled people?!

So what am I missing here? Is it really ableist to ever even consider supporting transport solutions other than each individual driving a single private car? Do we have to put up with all the fatalities caused directly by too many cars and indirectly by climate disaster forever because doing anything about it at all is ableist? My feeling is that what's ableist is making isolated changes without thinking through the consequences in an integrated way, but refusing to even imagine a better approach doesn't seem like the right answer.
