Uber has finally deployed its first fleet of driverless vehicles in Pittsburg, Penn., but only so-called “loyal” customers will be able to give them a whirl. This deployment was only two years after Uber made its intentions of having driverless vehicles to pick up passengers known, which the CEO initially said would take decades to really come to fruition. As a result, the future that Uber drivers feared, where they would become obsolete is coming much sooner than promised.

Right now, only a few passengers are eligible to be picked up by driverless Uber cabs in the city, and only for select destinations. The vehicles themselves are equipped with a carload of contraptions to help it maneuver the busy streets of Pittsburg, including traffic light sensors, 3D-mapping lasers, and a weather detection system, ABC News reports.

As for the cars themselves, the front seats are occupied by an engineer and a “safety driver” behind the wheel to intervene should anything go wrong or if there is anything that needs calibration. This provides passengers who have tried the service an experience that is practically no different to hailing an Uber cab that does have a driver.

One interesting development with regards to driverless cabs by Uber, according to Recode, is the fact that the company now owns physical assets. With the old system, the cab hailing service owned no cars because the drivers had to have one already. Now, Uber needs to have actual vehicles, which will be outfitted with all of the sensors necessary to become autonomous.

It’s also worth noting that Uber CEO Travis Kalanick assured drivers in 2014 that self-driving vehicles would take decades to actually take off. Just two years after he made this assurance, driverless cars are now hitting the streets and threatening to make actual Uber drivers unemployed.
