Tesla, $TSLA, plans to delay Robotaxi unveiling to October from August

Tesla is delaying the launch of its robotaxi by about two months to October, as the design team was instructed to rework some elements of the car, Bloomberg News reported on Thursday, citing people familiar with the decision.

Shares of Tesla, which is betting on self-driving vehicles over less-expensive cars, closed down more than 8% at $241.03 on Thursday following the news, ending 11 straight sessions of gains that had pushed the stock up 44%.

Tesla did not immediately respond to a Reuters request for comment.

Elon Musk had announced the Aug. 8 unveiling date for the robotaxi after Reuters reported on April 5 that Tesla had canceled its long-promised inexpensive car and would continue developing self-driving robotaxis on the same small-vehicle platform.

"Tesla has been playing this game for nearly a decade of promising 'next year, next year.' And I've seen no indication that Tesla is on track for a meaningful deployment of the kind of automated driving system that Tesla has consistently promised," said University of South Carolina law professor Bryant Walker Smith, who specializes in autonomous vehicle law.

Except for announcing an unveiling date, Musk has given minimal details about the robotaxi so far. He has only said that some vehicles will be owned and operated by Tesla, while others will be owned by individuals but rented out on Tesla's network.

Analysts and industry experts have said the race to develop autonomous driving systems and robotaxis will be arduous and take years as the technology faces engineering and regulatory hurdles.

"I think the (launch) event will be a disappointment as we were probably going to get a CyberTaxi, not a RoboTaxi. Nobody's going to be able to knit socks on their way to work or nap while the vehicle brings you to grandma's," said Craig Irwin, senior research analyst at Roth MKM.

Still, some investors said they were not overly concerned by the delay.

"Honestly, it seemed like a quick pivot, so I'm not surprised by the delay at all. In the grand scheme of things, two months don't change the picture," said Jamie Meyers, senior analyst at Laffer Tengler Investments, which holds positions in Tesla.

"I actually think it's a good thing that Elon and company are getting their ducks in a row to do this launch right."

Musk has been focusing on artificial intelligence, autonomous driving software, robotaxis, and the humanoid robot named Optimus to combat a slowdown in EV sales, which generate more than 80% of Tesla's quarterly revenue.
