Radar Scanners positioned around cars are able to find targets around the car, truck, etc and move out of their path. In test drives Nissan’s cars passed the test to be fitted with this technology are able to swerve out of the way of a people around that walks, runs, etc into its way, missing the person and saving their life. Like something from a movie it seems as though the future is now with this technology.
