There are bikes for handicapped people. And if cognitive issues are a thing, then cars would be far more problematic: crash a bike into a person, you get minor wounds. Crash a car into a person, and you get a death caused by the car driver (who sometimes gets off scot free).

And if something is ableist, it’s cars for disabling you from walking/wheelchairing anywhere safely due to the stroads taking up all the space.
