China has granted Chinese internet services company Baidu and a rival autonomous car company, Pony.ai, permits to provide driverless ride-hailing services to the public in Beijing, a significant regulatory step in the country’s pursuit of driverless technology.

The permits given to Baidu and Pony.ai allow them to offer rides without a safety driver behind the wheel to take over in cases of an emergency. The new permits still require a safety supervisor to be seated in the front passenger seat.

Baidu said 10 such autonomous cars began offering rides to passengers within a 60-square-kilometer (23-square-mile) area in suburban Beijing from Thursday.
