Carwings. Now, Nissan is gearing up to launch two safety pilots which will rely on -- you guessed it -- Carwings HDD navigation systems. First up is the slip-hazard alert, which marries data from the ITS (Intelligent Transport System) and ABS (Anti-lock Braking System) in order to warn drivers of slippery road conditions. In addition to that, the recently concocted road-cam service can "enhance the effectiveness of the alert service by offering drivers a visual image" of surroundings. The company will make the slip-hazard alert and the new road-cam service available to all Carwings customers (in Japan) beginning next month, with the latter hitting first (in November) and the former second (in December). Oh, and did we mention the upgrades will be completely gratis? Because they will be.
