For street and community livability, Autonomous Vehicles (AVs) potentially offer the benefits of more street space for cyclists and pedestrians, and reduced demands for parking. But to realize these promises, planners need to achieve two key objectives: more (vehicle) sharing, and less sprawl.

If we cannot do these two things, the induced travel and sprawl effects of AVs (driven by the vanishing personal cost of travel) will likely drive up vehicle travel and capacity requirements beyond the ability of cities to provide this new street livability space for human travelers.
