Renault-Nissan boss Carlos Ghosn says that self-driving cars could arrive on the roads before 2018, if legal issues don't get in the way. They've already created the Next 2 prototype version of the Zoe EV which allows drivers to let go of the controls at speeds below 30km/h.

Nissan is also working on autonomous driving technology and said it would bring self-driving vehicles to market by 2020.

“The problem isn’t technology, it’s legislation, and the whole question of responsibility that goes with these cars moving around... and especially who is responsible once there is no longer anyone inside,” Ghosn was quoted as saying by Reuters at a French Automobile Club event.
