May 29 (Reuters) -

Tesla has been testing driverless Model Y cars in

Austin, Texas and aims to deliver the first unit in June, CEO

Elon Musk said on Thursday, amid buzz of an imminent robotaxi

launch.

Musk had said earlier this year that such a launch would

start with 10 or 20 Model Y vehicles.

"A month ahead of schedule," he said on Thursday in his

X post, adding that the tests had not seen any "incidents."

He had previously said that Tesla aimed to begin tests

of robotaxis only by the end of June.

While the billionaire, who had just hours ago said he

was leaving U.S. President Donald Trump's administration, did

not give a timeline for the launch, Bloomberg News had reported

that Tesla aims to launch its robotaxi service in Austin on June

12.

Tesla did not immediately respond to a Reuters request

for comment outside of regular business hours.

Musk said on Wednesday he was leaving U.S. President

Donald Trump's administration where he lead a tumultuous

efficiency drive, upending several federal agencies and

ultimately failed to deliver the generational savings he had

sought.

Tesla sales have fallen worldwide with rising

competition and as Musk faces a backlash for his right-wing

political views and his work for Trump.
