Hands on: How self-drive cars will tell you to take control
The everyday workings of a self-driving car have just been revealed by Volvo. A new interface, called IntelliSafe Auto Pilot, has been shown working in an XC90.
Paddles on the steering wheel light up when the car reaches a portion of the road approved for autonomous driving.
When you put your hands on the panels for a certain amount of time, the car takes over the driving functions.

Should you not re-take control the vehicle brings itself to a halt.
