Nissan for several years now has been developing autonomous driving technologies, with a goal to introduce truly autonomous driving by 2020.
While assisted driving (that requires driver attention), is soon to be introduced on more and more models, full autonomous transportation would free up the driver to do something else while behind the wheel - like "help the kids with homework" on the way to school.
The most common test mule for Nissan, in both the U.S. and Japan, is the all-electric LEAF.
"Introducing Nissan Intelligent Driving with Piloted Drive
Nissan Intelligent Driving with Piloted Drive helps you drive smarter, safer, and with more confidence. Without the stress and inefficiency of driving as you know it, Piloted Drive makes it easy and fun to get around.
At Nissan, our mission is to make driving more enjoyable and safer. Not just for a few, but for everyone. By 2020 you’ll find multiple models with Piloted Drive in major mass production in the US, Japan, China, and Europe."
