With this idea he could help achive that goal. Another point is that according to charts and studies it shows that people are driving less and each year the amout of people to get there licence is decresing. The US took this in to notice and they belive that eventually more and more place will become these car-free places. Even car companys like Ford are looking in to this, "car-reduced" plan. They seem to think its good for the people and will eventully put this plan into affect. It seems the less we use cars the better things are getting.
