The days of self-driving cars just got closer with Nissan's EPORO, robot cars that know how to move together without colliding. Nissan's built robot cars before, but says this is the first time such vehicles have been able to travel together as a group, zipping around like a school of fish and avoiding obstacles, as well as each other.

These research bots are blazing the trail towards Nissan's ambitions of creating collision avoidance technology to be used in vehicles. We're thinking this is a huge step toward building cars that drive themselves. In the meantime, a group of six of these EPORO bots will be traveling around in close formation next week at CEATEC Japan, 2009.
