No private cars in the development? OK, that means the housebound can't live there, because people like home health nurses can't be asked to drag equipment and other supplies from the closest parking to wherever the person lives. With many First-World countries looking at aging populations, this is going to limit the appeal of such developments.
Aging populations are exactly a reason to move away from car dependence. Instead they're trapped in suburban homes with no drivers' licence, often alone.
Old people should be in communities where driving is de-emphasized, I agree. However, home health services promote independence, too, and they depend on cars to practically transport meals, equipment, and people directly to the door, in ways which would be vastly impractical if cars were outright banned.
