writes "The current test vehicle uses what Nissan calls its "Advanced Driver Assist System," which isn't fully autonomous, but rather can be thought of as a really advanced cruise control system. According to the company, the system can keep a car in its own lane, while automatically changing lanes to pass slower vehicles or prepare to exit a freeway, which it can also do automatically. Along with that, the car automatically slows for congestion, and—most impressively in my opinion—can automatically stop at red lights.
In other words, the car isn't fully automatic in that you can't simply type in a desination and have it do all the work, but the bulk of driving load is taken care of. Curiously, Nissan's goal appears to be to take sloppy human drivers out of the equation to eliminate road fatalities."Link to Original Source
