Last year I was quite enthusiastic about Waymo, Google’s self-driving cars that have been on their way to DC for quite a while now with no go-live date in sight. Well just this week I was in San Francisco again and the difference in experience was striking. Last year I had a family member or two with me so it was never a one-person ride. This year I came by myself, and felt lonely sitting in the back seat of a large Jaguar. I couldn’t look at the phone — those dots don’t really help with motion sickness — so I just listened to a podcast while staring through the window.

In contrast, I had excellent conversations with every taxi and Lyft driver on this trip. But I’ll skip recounting those lest I turn into Tom Friedman.
