Elon Musk had a lot to say about Tesla’s upcoming Robotaxi service on Wednesday. Robotaxi will be coming to Austin and other cities later this year, Musk claims.

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.

Tesla plans to launch its robotaxi business and pilot production of its humanoid robot in 2025, the company said Wednesday. Why it matters: CEO Elon Musk has described self-driving car services as critical to the company's future.
