This advanced cruise control/lane keeping assist now allows hands-off driving in a single highway lane, while constantly monitoring the driver's attentiveness, as the system will need the driver to take over in a sudden situation. With a pre-defined route activated on the navigation system and relying on a suite of cameras and radars, the ProPILOT equipped Skyline is able to change lanes and choose the correct ramp; at the highway exit ramp, the system prompts the driver to take full control of the car, both with audio and visual cues.
The driver authorizes the suggested moves by placing their hands on the steering wheel and pressing a switch, and in the event of a lane change to overtake a slower-moving vehicle, by using the turn signal. Nissan calls the hands-off driving capabilities a "world first", but like Engadget points out, the Cadillac SuperCruise also allows driving hands-off in a single lane, as long as a lane change isn't needed. The hands-off mode will not be available in two-way traffic, tunnels, toll areas or "winding roads", according to Nissan.
The "navigated highway driving" assist will be made available on the Skyline series in the fall of 2019; presumably, this means the premium sedan line and excludes the GT-R. No corresponding U.S. market Infiniti availability has yet been announced.
