TOKYO -- Nissan Motor has upped the autonomous driving ante. The company on Wednesday became Japan's first automaker to release a vehicle capable of maneuvering itself, albeit only in a single expressway lane. And it opted to introduce the technology in a family car, rather than a high-end model.
In giving its Serena minivan the first major update in six years, Nissan included a system it calls ProPilot. A camera affixed inside the windshield measures the distance to the car ahead and judges the vehicle's position within the lane.
