TESLA HAS AUTONOMOUS RIDE-HAILING SERVICE IN PIPELINE: WHAT TO KNOW

Tesla learned on Sunday from the China Association of Automobile Manufacturers that its Model 3 and Model Y vehicles met data security standards required in the country. The company produced over 1.77 million Model 3 and Y vehicles over the course of 2023.

The Wall Street Journal reported Monday that Tesla had received indications China was giving the go-ahead for the EV maker’s Full Self Driving software. It currently does not offer FSD there.

FSD gives "access to a suite of more advanced driver assistance features" than Autopilot "designed to provide more active guidance and assisted driving under your active supervision," per Tesla’s website.

Musk has been to China in the past. He went for three days in 2023, speaking with the country’s foreign minister and going to Gigafactory Shanghai, as FOX Business reported at the time.

He more recently interacted with Chinese President Xi Jinping at a reception held in San Francisco in November.

China remains a large market for Tesla despite facing competition from many local automakers.
