A year and a half ago, Uber set up an Advanced Technologies Center (ATC) in Pittsburgh to make self-driving Ubers a reality. Today, we’re excited to announce that the world’s first Self-Driving Ubers are now on the road in the Steel City.

We’re inviting our most loyal Pittsburgh customers to experience the future first. If a Self-Driving Uber is available, we’ll send it along with a safety driver up front to make sure the ride goes smoothly. This pilot is a big step forward. Real-world testing is important to the success of this technology.

Self-driving Ubers have enormous potential to improve society: reducing the number of traffic accidents, which today kill 1.3 million people a year, and freeing up the 20% of space in cities currently used to park the world’s billion plus cars. In addition, self-driving Ubers will be on the road 24 hours a day, which means they’ll need a lot more human maintenance than cars today. As a result, more people have to be employed.

We know a large number of drivers will have questions about this technology. It’s still very early: Self-Driving Ubers have a safety driver in the front seat because they require human intervention in many conditions, including bad weather. Even when these technology issues get fixed, we believe ridesharing will be a mix—with services provided by both drivers and Self-Driving Ubers. This is because the limits of self-driving software and the increasing demand for better transportation.

We couldn’t be more excited about what’s next. But to make it happen, we need to lead by fusing our great ridesharing network with great self-driving software and hardware. Our ATC efforts mean we have one of the strongest self-driving engineering groups in the world. And our existing partnerships with drivers, as well as new ones with manufacturers like Volvo, will ensure a world-class customer experience for generations to come.
