San Francisco officials are calling for state regulators to make Uber and Lyft trip records public, including data on collisions and assaults in the city.

District 7 Supervisor Myrna Melgar, who chairs the San Francisco County Transportation Authority, said cities need the figures to address public safety, plan for traffic and design transit. The California Public Utilities Commission recently voted to postpone the release of six years of trip data while it reconsiders Lyft’s latest request to withhold it.

The commission regulates ride-hailing and receives annual company reports covering trips, collisions and assaults. It has collected the data since California legalized ride-hailing in 2013 but has released little, citing confidentiality in response to repeated requests from local officials.

Drew Cooper, a senior analyst at the transportation authority, said the lack of data makes it hard to gauge changes in ride-hailing as autonomous vehicles grow and travel patterns shift after Covid.
