You know that feeling of technological dominion when you use Waze or some other navigation app, and you beat the projected arrival time? I felt this way a few weeks ago, when driving 90 minutes from Washington, D.C., to Chestertown, Md. I’d driven from Pittsburgh to D.C. for an event, stayed two days in a hotel, and then drove to speak at Washington College in Chestertown. I had to make it to a 9 a.m. creative writing class, so I left my hotel at 6:30 — inserting a time cushion in case I was swallowed by the notorious Beltway traffic. But my drive was so linear (and, occasionally, illegal) that I beat Waze by seven minutes, arriving at 8 a.m.
