There are no fully self-driving cars on sale today. Any vehicle with a semi-autonomous system -- whether Cadillac Super Cruise, Tesla Autopilot or something else -- requires the driver to pay attention and take over at a moment's notice. But by 2021, Volvo hopes it'll have a car so advanced that a driver could nap behind the wheel while the car drives itself.

Speaking at the launch of the S60 sedan yesterday, Volvo Senior Vice President Henrik Green told The Car Connection that the next-generation XC90 SUV would offer Level 4 self-driving technology by 2021. The goal is for the system to allow for "sleeping passengers" when driving on certain limited-access highways.
