The Mack Institute asks
Before 1 January 2020, will General Motors launch a ride-hailing service open to the public in the U.S. which uses autonomous vehicles?
General Motors and its subsidiary Cruise Automation have announced intentions to launch a ride-hailing service somewhere in the U.S. in 2019 (GM Authority). GM plans to use a version of the Chevy Bolt built without a steering wheel for the service (Detroit News, Driven, IEEE Spectrum). However, technical and regulatory hurdles remain (Reuters, San Francisco Chronicle). A service which requires rider prescreening or registration before use will count. A service that operates along a fixed route will not count.
The question closed "No" with a closing date of 1 January 2020.
