Uber's self-driving cars have been transporting people around Pittsburgh for over two months now.

Uber reached out to roughly 1,000 regular users when it first launched the pilot program in September, asking if they would like the opportunity to hail a ride in a self-driving car. The program has since expanded the scope of the pilot, but Uber won't provide specific numbers as to how many people got an invite.

But we do know two Pittsburgh steelers got a chance to ride in one per a promotional Uber video and thought the car did a "really good" job.

We also got a chance to ride in a self-driving Uber in September — here's a look inside.
