As autonomous cars strive to make sense of the world around them, they collect massive amounts of data, including traffic and congestion patterns, where pedestrians cross the street, which houses and businesses have Wi-Fi, and other details, which could be monetized. While companies may have intellectual property and other economic interests in protecting geospatial data, local governments, private citizens and other actors also have a vested interest in using that data to inform decisions on managing traffic, urban planning, allocating public funds and other projects, all of which may be of public interest.

"Self-driving cars have the potential to transform our transportation network and society at large. This carries enormous consequences given that the data and technology are likely to fundamentally reshape the way our cities and communities operate," explains study author, Luis F. Alvarez León, an assistant professor of geography at Dartmouth.
