Tesla has started giving rides in driverless Model Y SUVs in Austin. Details are still sparse, but limited service is open to vetted and invited riders.

Elon Musk's Tesla enters the self-driving taxi game, an industry with big names like Waymo and Zoox in the U.S.

The automaker deployed a small fleet of self-driving taxis in Austin, Texas, on Sunday, marking the first time its cars have carried paying passengers without human drivers. The rides were being offered for a flat fee of $4.20 in a limited zone.
