Tesla is “very close” to developing fully autonomous vehicles and could work out the basics of that technology as soon as this year.

Bloomberg reports that CEO Elon Musk made the comments a prerecorded video played during the World AI Conference in Shanghai.

He reiterated previous comments that the electric vehicle maker has solved most of the essential challenges towards achieving Level 5 autonomy that needs no human behind the wheel.

“I’m confident that we will have the basic functionality of L5 autonomous driving this year,” he said. “There are no fundamental challenges.”
