Talk of Tesla hogs the conversation around autonomous vehicles lately, so you might be surprised to learn how far Cadillac has come in the self-driving department. GM’s Super Cruise system, launched on the CT6 sedan, can pilot the car for minutes—hours, even—with your hands off the wheel.
We took a CT6 equipped with the system to Texas Highway 130—also known as the fastest road in America (speed limit 85)—to test it out. Like Tesla’s Autopilot, the Super Cruise system uses radar and cameras to locate lane lines, other vehicles, and obstructions. It also adds 130,000 miles of 3-D laser-mapped roads to pinpoint the exact location of your car within a few inches, and it knows what’s ahead.
A camera on the steering column tracks your head motion to ensure you’re paying attention and, when adaptive cruise is active on limited-access highways, a light on the steering wheel turns blue. Push a button and it “takes the wheel.” We went minutes between wheel touches but had to resume control in construction zones or when lanes widened at an exit. Super Cruise is not perfect—attention is still required—but it’s a peek at the future, for sure, and you can drive it today.
