Quote from Learning from Las Vegas

A driver 30 years ago [written in 1977] could maintain a sense of orientation in space. At the simple crossroad a little sign with an arrow confirmed what was obvious. One knew where one was. When the crossroads becomes a cloverleaf, one must turn right to left…But the driver has no time to ponder paradoxical subtleties within a dangerous, sinuous maze. He or she relies on signs for guidance – enormous signs in vast spaces at high speeds.
