Nissan unveiled a unique twist on autonomous driving technologies at the Consumer Electronics Show in Las Vegas today, bringing the use of remote human intervention as a way of solving the current limitations of artificial intelligence (AI) in cars. As part of its Seamless Autonomous Mobility (SAM) system, Nissan claims it will allow its car's AI to use cloud processing power as well as the ability to call on help from human support (in a remote centre) to help it overcome unpredictable situations. The idea, according to Nissan, is to allow for a transitional phase whereby autonomous cars can begin to coexist with human drivers. When the autonomous driving system of a car comes to a situation that it cannot process or deal with, such as an accident site, or roadworks, it will either hand the case over to the driver, or if not possible, it will contact a remote command centre which would take charge of the situation, remotely log-in to the vehicle and draw a route around the obstacle for the car to follow. The reason for this human intervention requirement, Nissan boss Carlos Ghosn says, is because drivers know how to break the rules respectfully, but machines do not.
