YEREVAN, SEPTEMBER 15, ARMENPRESS. When Pittsburgh wakes up on Wednesday morning, some residents will have the choice of going about their day in an Uber that drives itself, “Armenpress” reports, citing Reuters.

The launch of Uber's self-driving pilot program marks the public unveiling of the company's secretive work in autonomous vehicles and the first time self-driving cars have been so freely available to the U.S. public.

More than two years ago Uber - like most in the car business - identified autonomous driving technology as the springboard for the next stage of growth.

The aggressive San Francisco-based startup has already shaken up the world’s taxi services, earning a valuation of $68 billion. It plans ultimately to replace many of its 1.5 million drivers with autonomous vehicles.

But it is not as if robots are taking over the Steel City. There will be only four self-driving vehicles available to passengers, to start, and two people will sit in the front to take over driving when the car cannot steer itself.

Uber provided ride-alongs to reporters on Tuesday. During a ride of about one hour, Reuters observed the Uber car safely - and for the most part smoothly - stop at red lights and accelerate at green lights, travel over a bridge, move around a mail truck and slow for a driver opening a car door on a busy street. All without a person touching the controls.

But the Uber driver and the engineer in the front two seats did intervene every few miles.

Since opening its Advanced Technologies Center in Pittsburgh last year, San Francisco-based Uber has moved quickly, hiring away some 40 faculty and researchers from Carnegie Mellon University - a move that ruffled feathers locally - and forming partnerships with automakers including Volvo.

But the company is competing in a crowded field. From Alphabet Inc (GOOGL.O) and Baidu Inc (BIDU.O) to Tesla Motors Inc (TSLA.O) and General Motors Co (GM.N), technology companies and automakers are hustling to build autonomous vehicles and develop new business plans for what is expected to be a long-term makeover of personal transportation.

By integrating self-driving cars with its ride-services app, Uber may be the first introduction to autonomous cars that many people will have.
