> Same thing that happened pre-COVID with "ridesharing"

Fifteen minutes in an Uber is far more pleasant, productive, and I’d wager healthy, than ten minutes in gridlock. I can focus intensely on a task or thought or even take a nap.

We should also build rail. But self-driving cars look more likely to complement rail than detract from it. (One can imagine multi-modal trains, onto which self-driving cars park so their owners can enjoy privacy and a custom interior alongside the economics and eco-friendliness of rail.)
