No, but if we drove less with cars, the amount of people with fit and healthy legs would increase. Also, there are plenty of other vehicles for those, who can't walk, which are allowed in pedestrian zones. As well as exceptions for people being dropped off, who qualify as handicapped.
What percentage of people do not? 1%?
Probably 10%+ if you include the elderly and others who can’t comfortably walk a mile or two
So 1 percent minorities don't matter to you? Good to know.
