If we do not voluntarily initiate car-free models of social development, we will be forced to create them over the century as the costs of alternatives ascend. The result will be less appealing than if we think ahead and model them ASAP.
The same old same old is not a long term option. It will hold for a minimum of two generations. After that we will be lost in a world where the one percent lives in gated isolation It is urgent that Occupy folk and others begin to add car-free to their lexicon and ponder what sort of living this portends.
