Austinites may soon be able to hop in a Tesla robotaxi, as Elon Musk's electric vehicle maker targets a possible June 12 launch and has already started testing its driverless Model Y vehicles in the city.

City officials say they're unaware of Tesla's plans to roll out self-driving taxis in Texas, according to reports.

The EV maker will roll out about 10 self-driving cars next month and scale up to about a thousand, Musk told CNBC in an interview.
