Tesla’s Austin robotaxi service will kick off with 10 vehicles and expand to thousands, moving into more cities if the launch goes well.

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.

Tesla is currently testing its self-driving Model Y cars in Austin, and residents may see the launch of the EV-maker's robotaxi in June.
