For me, car driving was a waste in many ways. While others focused on the negatives of pollution and petroleum costs, I could not fathom the human waste involved—not the excrement kind; rather, I mean that the average American spends sixteen hundred hours driving a car every year. Sixteen hundred hours of rapt, pointless attention. Assuming other brains work like mine, we each have only a limited number of hours of serious concentration in us each day. If four hours of that shockingly scarce resource are wasted daily on left and right turns, it is little wonder that civilization was waning.
