The autonomous vehicle revolution promises three enormous benefits: millions of avoided deaths and maimings, more productive uses for the vast amounts of land we currently devote to parking (and gas stations, auto repair shops, dealerships, etc.). And most obviously, much cheaper mobility, which is straightforwardly a good thing. So it can be transformatively great, but we really do have to mitigate the big downside — a huge increase in traffic and congestion.

Autonomous driving gives us a rare opportunity to prevent future traffic nightmares and steer the future of mobility towards the public good.
