What is our plan for zero-occupancy vehicles?

A common techno-utopian vision of the near-future city is one where automated vehicles come when called and whisk you to your destination, as you sit, relaxed and untroubled by traffic. But consider the opposite vision, that gridlock will be made worse by autonomous vehicles, which will spend much of their time driving around the city with no passengers. There is simply nothing about a vehicle being autonomous that makes it more likely to achieve higher occupancy. In fact, the current trajectory of AV deployment roadmaps and our transportation policy response ensures its average occupancy will be lower.
