The big timeline of Uber’s 2 years of testing self-driving cars in Pittsburgh

Two years ago, reporters from across the country flocked to Pittsburgh for two days of secretive media briefings on a new pilot program from Uber.

The company had opened its Advanced Technologies Group here the previous year and was already testing autonomous cars on Pittsburgh streets. But two years ago Friday, Uber started allowing ride share users to be picked up and dropped off in its self-driving cars.

While Uber wasn’t the first autonomous vehicle tester in Pittsburgh — or the latest one — the company has been the most visible, both on the streets and in headlines. But Uber paused testing for nearly four months this year after a fatal crash in Arizona, effectively ending the pilot program for riders for now.
