Nissan is introducing some new, advanced driver assist systems for the Japanese market Skyline sedan this fall. Similarly to Tesla's Navigate on Autopilot, the updated ProPILOT system now combines navigation and automatic lane-changing. In addition, hands-off driving is enabled when certain guidelines are met and the driver is paying attention to the road ahead. Earlier ProPILOT iterations have required the driver to keep a hand on the wheel at all times.
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.

Volvo will limit top speed on all its vehicles to 112 mph
Volvo has announced that it will limit the top speed of its cars to 180 kph, or 112 mph. The carmaker says it wants to send "a strong signal about the dangers of speeding," and from 2020, no Volvo cars can go faster than that. The limit is part of Volvo's Vision 2020, which aims for zero road deaths or severe injuries in a Volvo by 2020. Polestar models were not mentioned.
"Volvo is a leader in safety: We always have been and we always will be," said HÃ¥kan Samuelsson, president and chief executive. "Because of our research, we know where the problem areas are when it comes to ending serious injuries and fatalities in our cars. And while a speed limitation is not a cure-all, it's worth doing if we can even save one life."
Volvo's flagship XC90 SUV currently has a top speed of 131 mph.
Samuelsson, speaking ahead of the Geneva Motor Show, said it is unlikely to meet the Vision 2020 goal without additional measures to address driver behavior.
"We've realized that to close the gap we have to focus more on the human factors," Samuelsson told Reuters. Volvo did not elaborate on the data but said its passenger fatalities were already well below the industry average before the goal was announced in 2007.
In addition to the speed cap, Volvo plans to deploy technology using cameras that monitor the driver's state and attentiveness to prevent people driving while distracted or intoxicated, two other big factors in accidents, Samuelsson said.
There's also nothing preventing these Volvos from being driven at 60 mph in a 30 mph zone yet, except for proposed EU-mandated automatic speed limiters. But Volvo is also looking into limiting lower speeds with technology. Volvo's statement says: "Apart from limiting top speeds, the company is also investigating how a combination of smart speed control and geofencing technology could automatically limit speeds around schools and hospitals in future." In other words, if drivers cannot be trusted to make the decision to slow down, the cars will do that for them.
It has to be said the 112 mph limit is somewhat peculiar. Even if Japanese home market cars have had the same speed limit implemented for ages, there aren't that many countries where you can legally pass 110 mph. European highway limits are usually around 75-80 mph at maximum, and crashing at 90-100 is already dangerous enough. It feels like Volvo has set a limit no one would ever reach in normal driving, except perhaps on the German Autobahn. Samuelsson conceded that the limit could be a turnoff for German buyers.
That also brings us to an another aspect of the matter: which more strongly affects sales, a message that a manufacturer voluntarily limits its cars from reaching a certain speed, or that the cars are guaranteed to attain a given speed that few buyers ever reach?
"We cannot please everybody, but we think we will attract new customers," the CEO said, recalling that the roll-out of three-point seat belts pioneered by Volvo in 1959 had initially been criticized by some as intrusive.
"I think Volvo customers in Germany will appreciate that we're doing something about safety," he said.
