In turn, we should rely on walking, cycling, bus or train. Granted, this wouldn't be too much of an adjustment for larger areas where stores are closer together and parking is limited - like New York where citizens walk almost everywhere - but in a city like Killeen, Texas, all stores are extremely scattered. No longer having vehicles would require a reduction in family size, as one can only imagine the constraints and stress of having to walk or travel by bus with many children. Some parents currently have difficulty traveling with a child by car. Since they will no longer have this luxury, society will adapt and have fewer or no children. The difficulty of transporting a baby and a car seat while traveling great distances is immeasurable, and transporting that same car seat from one bus to another is a real headache. At one time, when cars remained extremely popular, flying was a faster but more expensive means of transportation. Yet when the United States becomes an automobile-free society, this will no longer be the case. No longer could you drive an hour down the road to visit family on impulse; that would require planning for tickets and other expenses. However, as flying is one of the only travel options, prices would surely come down from their once inflated price.
