In case you haven’t heard of ProPilot Assist or just forgot about it, the feature is a semi-autonomous driving system that provides steering, acceleration and braking assistance on highways. It can bring the car to a complete stop and resume accelerating up to speed, it recognizes other cars and adjusts speed, and it keeps the car in its lane. It does require the driver to continue paying attention and to keep hands on the steering wheel. Also, while it can handle some corners on highways, there are limits to how tight a corner it can manage.
The feature is currently available on the Nissan Rogue crossover SUV and the new Leaf EV. This will make the Altima the third Nissan-badged vehicle to get the technology. Our experience has been that even with ProPilot’s limitations, the feature works simply and reliably and is handy for long, boring highway journeys. So it should be a tempting feature on the new family sedan.
