If there is somebody who can’t walk, can’t bike, and can’t take alternative transit options (eg, disability-supported shuttle, or plain buses) I do not see a car as a solution for them and would be worried about their driving cohesion.

The handicap argument has been tried against walkable city infrastructure for a long time. It’s a terrible dog whistle; the pressure to use a car to get everywhere is hurtful to the disabled as well as the rest of us.
