General Motors’ Super Cruise has been compared to Tesla’s Autopilot in an evaluation of 17 vehicles equipped with driving assistance systems by Consumer Reports. The Tesla Model Y with Autopilot feature finished second to Cadillac CT6 that was equipped with Super Cruise, which GM is rolling out to more than 20 vehicles, including its new Hummer electric pickup truck. Experts in safety and insurance has warned about the risks of consumers relying too closely on ADAS systems and their abilities. Many automakers call their products Autopilot, ProPilot or Co-Pilot, leaving consumers with a false sense of complete security.

Two years ago, the Cadillac CT6 with Super Cruise scored higher than a Tesla Model 3 with Autopilot, in a Consumer Reports test of just four vehicles equipped with ADAS.  Now in the most recent test that was conducted in summer on a track as well as on public roads, the Cadillac scored 69 points out of a possible 100, while the Tesla scored 57. A Lincoln Corsair vehicle that was equipped with Ford’s Co-Pilot 360 system scored a 52.

The critical difference in the Super Cruise system is a driver-facing infrared camera to make sure he or she is paying attention to the road and is ready to take over manual control when necessary, said Kelly Funkhouser, head of connected and automated vehicle testing at Consumer Reports. The group noted that Autopilot can shut off abruptly in some situations, while Super Cruise did a better job of notifying the driver when the system is disengaging.

In similar tests concluded in Europe, a Tesla 3 with Autopilot placed sixth out of 10 systems, with high marks for performance and ability to respond to emergencies but low marks on maintaining driver’s ability to focus on the road. “The features might be cutting edge, even cool, but we think buyers should be wary of shelling out $8,000, or potentially $10,000 soon, for what electric car company Tesla calls its full self-driving capability option,” the report said.
