This is probably one of the fundamental questions to how the future of AVs will roll out.  This article from Slate looks at three basic scenarios of AV ownership and use: Private ownership (what we have now), fleet ownership for private rides (think Uber/Lyft), and fleet ownership for shared rides (think Uber Pool).

While the article lays out convincing parameters for these scenarios, it doesn’t address the potential for differentiated models based on density.  Cities may lean towards fleet ownership and/or shared rides, but as we move further and further out into the suburbs, fleet management will be more difficult to do efficiently and profitably.  This seems like it would push towards more private ownership in these locations. If so, some of the parking related benefits of AVs – to name only one of many issues – may be uneven across urban areas.
