It may be the physical infrastructure required to keep millions of autonomous vehicles operating—and the commercial real estate underneath it. The conventional assumption is that this infrastructure will resemble fleet infrastructure today: large, permanent depots located where land is relatively inexpensive. Some of the same sites that once supported human-owned vehicles could become the distributed operating network supporting autonomous ones. A strategically located, fleet-neutral operating network can potentially serve multiple autonomous vehicle platforms, much as cell towers support multiple carriers and data centers support many technology companies. Today, he is applying that experience to the physical operating infrastructure required to keep autonomous fleets running efficiently at scale.
