Elon Musk says Tesla's latest full self-driving software is 'not great' and that engineers are racing to improve it

• Elon Musk said the latest version of Tesla Full Self-Driving (FSD) was "actually not great."
• FSD partially automates driving so the car can change lanes, park itself, and recognize traffic lights.
• The Tesla CEO said the company was racing to improve beta version 9.2 "as fast as possible."

Elon Musk said on Monday that the latest version of Tesla's Full Self-Driving (FSD) software, which partially automates driving, was "not great," and that the company was racing to improve it.

"FSD Beta 9.2 is actually not great," Musk wrote on Twitter, adding that the electric car maker was "rallying to improve as fast as possible."

Musk wrote in a follow-up tweet hours later that he'd tested FSD beta version 9.3, which hasn't yet been released, by driving from Pasadena to Los Angeles International Airport, and that it was "much improved."

Tesla rolled out the long-awaited beta version 9 (v9) of its FSD software in July, but told drivers that the software "may do the wrong thing at the worst time."

One day before the release, Musk wrote in a tweet that drivers should be "paranoid" when driving with the software.

FSD is an enhanced version of Autopilot, a driver-assistance software that comes with every Tesla vehicle. FSD, which doesn't make the car fully autonomous, allows the vehicle to change lanes, park itself, and recognize traffic lights and stop signs.

The billionaire's tweet comes one week after US safety regulators launched a probe into the electric car maker's Autopilot following 11 Tesla crashes with emergency vehicles.

FSD has also come under scrutiny. Beta testers have posted videos showing flaws and glitches with FSD, Insider's Tim Levin reported.

Tesla owners in the US can buy FSD for $10,000 upfront or $199 per month.
