Enhancing the car's on-board electronics and driver aids with information about the road, its statistical likelihood for accidents and slippery conditions at certain points, plus a 'road-cam' service that offers visual imagery of the road ahead - for instance, a mountain pass. By combining statistical data, near-real-time imagery and information transmitted from recent CARWINGS-equipped vehicles, such as the Nissan Teana, that passed over that area, the system can plot out a series of warnings and alerts about potentially slippery areas.
The slip-hazard system relays information from cars on the road to help improve overall safety
The slip alert system began actual testing in November 2007 on a 100-vehicle test fleet in Sapporo, Japan. The trial showed that by alerting drivers to the potential hazard, safety could be enhanced by slowing the pace of travel, and making driver's more vigilant and aware of their surroundings. There was even some evidence that the system's presence may have influenced drivers to continue their safe-driving tactics even in areas where the system hadn't alerted to a slip hazard.

Nissan's focus on advanced driving technology has been strong of late. Just a few weeks ago the company revealed a prototype collision-avoidance assistance system that is modeled on the principles bees use to navigate their complex environments.
