Tesla is expected to begin offering robotaxi service Sunday in Austin, an initial step that Elon Musk's backers believe could lead to the company's next growth wave.

Colombian billionaire Jaime Gilinski Bacal is open to selling his majority stake in British lender Metro Bank and has received interest from investors, two people with knowledge of the matter said.

In ramping up robotaxi service, Tesla is hoping to slingshot past Waymo, another autonomous car service that operates in Phoenix, San Francisco, Los Angeles and Austin, according to its website. Last week, Waymo applied for a permit to test its vehicles in New York City.
