Super Cruise is designed to ease the driver's workload on the freeway, in both bumper-to-bumper traffic and on long road trips by relying on a fusion of radar, ultrasonic sensors, cameras and GPS map data.
You seemingly can't glance up from the road without being bombarded with signs advertising petrol prices and headlines noting bumper profits for the oil firms.
The systems basically work the same: a series of cameras, lasers or infrared sensors integrated into the car (on the back side of the rear-view mirror, in the bumper or behind the windshield, for instance) monitors lane markings in the road.
