And these vehicles are now carrying passengers around Pittsburgh and Pennsylvania, just like any other Uber would. The San Francisco-based company has outputted more than a dozen Ford Fusion cars with lasers, cameras and GPS sensors so that they can sense the environment around them and drive safely to all kind of conditions, including snow, and bridges, and crowded streets. In the back of the car is a screen that passengers can swipe to begin the trip. and it also displays exactly what the car is seeing in real time through its ray of sensors Well, these cars represent today's state-of-the-art technology. They are not free of human just yet. Each self-driving car has two Uber employees in front. A back-up driver in the driver seat and an engineer who takes notes on each ride. So now, I am actually going to be able to test out one of these cars for myself and sit behind the wheel in one of Uber's self-driving cars. Let's see how it goes. (music) Uber's goal is for its cars to be fully autonomous and self-driving. But now human intervention is still needed sometimes. As I was driving, I had to keep my hands on the wheel and watch the road. In our ten-minute ride, I never needed to take over the car, but I was to told to keep my foot over the brake, just in case. So here I am behind the driver's wheel and... look at my hands. (music) So the ride was pretty smooth. The car could use blinkers and turn, brake, accelerate all that with no help from me. And when you are in the driver seat, you're supposed to keep your hands on the wheel just in case you need to take back control. The only thing car can't do yet is change lanes, but that's coming soon. (music) Uber is still building its fleet and plans to have dozens of self-driving cars available to passengers in Pittsburgh by the end of this year. In addition to the Ford Fusion like the one I rode in, they will also be introducing self-driving Volvos, which the company calls their second generation of self-driving cars.
