Tesla CEO Elon Musk announced that a fully autonomous taxi service will debut in Austin, Texas, this June, ensuring people that what we once thought of as science fiction is now reality.

Musk, who also runs SpaceX and a number of other companies, has been known to make big often exaggerated promises. For example, he once called the Hyperloop, which was never built, the "fifth mode of transport" and famously promised to take Tesla private in a Twitter post, saying he had secured financing that he didn't have.

Led by Elon Musk, Tesla is about to revolutionize the taxi market with its new autonomous Robotaxi service in Austin, Texas.
