DETROIT — During a presentation at the Detroit Auto Show, CEO Mark Fields announced Ford has an accelerated plan to expand its Chariot ridesharing service to six more cities this year, including one city outside the U.S., Inverse reports.

Chariot was a San Francisco-based start-up and Ford announced the purchase in September. The service crowdsources its routes based on rider demand, and it’s working to use data algorithms to map the most efficient routes, helping commuters who aren’t well-served by current public bus routes and local trains.

Fields, who also announced Ford’s plans to create a hybrid autonomous vehicle to use for ridesharing by 2021, did not yet announce which cities will partner with Chariot. For the full story, click here.
