text: The cars may be able to drive themselves but humans can still take control when necessary. If there is ever an environment where the car cannot navigate properly, like an accident or a work zone, the car will require the human driver to take over rather than taking its regular plotted course. "They can steer, accelerate, and brake themselves, but all are designed to notify the driver when the road ahead requires human skills". (Driverless Cars Are Coming) The notifications for the driver to take control are maximizing the safety of the driver and passengers. Unexpected changes in the path the car has been traveling may require human assistance which shows the driver can still be in control.
