Taxi drivers could soon be out of a job.

The world's first robotic taxi has hit the streets of Singapore.

Although currently just a trial phase, developer nuTonomy released the world's first autonomous taxi onto the streets of Singapore's business district on Thursday. The self-driving taxi, based on Mitsubishi's electric i-MiEV, is capable of piloting Singapore's busy streets on its own, but retains an engineer behind the wheel should anything go wrong.

"This is really a moment in history that's going to change how cities are built, how we really look at our surroundings," nuTonomy executive Doug Parker told Reuters.

During the trial phase the nuTonomy service is limited to a few people invited to download to the so-called "robo-taxi" app, but the company is hoping to rollout its automated taxi service to the general public by 2018. The company is aiming to have a fleet of 100 autonomous taxis by that launch date.

Although nuTonomy is the first company to get its autonomous taxi to the street, it certainly won't be the last. Volvo recently partnered with Uber to develop self-driving cabs and Ford has pledged to launch its own autonomous taxi service by 2021. Additionally, General Motors is working with Lyft on a similar initiative while Fiat Chrysler has partnered with Google's self-driving vehicle division.
