It will be at least 10 years before fully autonomous cars will be sold on world markets, Renault and Nissan CEO Carlos Ghosn said Monday.

"We'll be going from more simple to more complex forms of autonomous driving," Ghosn told Bloomberg television. "At the end of the journey we may end up with driverless cars, but I think that will be 10 years-plus."

Ghosn, who was talking to Bloomberg at the Mobile World Congress in Barcelona, said progress toward autonomous driving will have to overcome obstacles in the areas of technology, cyber security and regulation.

"Autonomous cars are a megatrend that's going to happen," Ghosn said, "but it will come step by step."
