When the Cadillac CT6 debuts GM's new Super Cruise autonomous driving system next year, it will boast an eye-tracking system, something none of its competitors can say.

According to the Wall Street Journal, Super Cruise's eye-tracking tech will monitor the driver-cum-passenger, checking if they are in fact following the rules and paying attention as promised.

For example, let's say you fall asleep under the lull of Super Cruise, the system will notice your gaze has gone and begin to aurally and visually poke you awake. Should that not work an OnStar rep will attempt to make contact, finally, if none of that works, the Caddy will casually pull off to the side of the road.

Monitoring the drivers eyes goes a step further than Tesla's Autopilot system, which requires periodic handling of the steering wheel to let the computer know everything is a-ok.

Lyndon Lie, GM's chief vehicle engineer for luxury cars, told Business Insider Super Cruise isn't like the others.

"We are taking a lot of lessons learned from our competitors and evaluating their cars as well," Lie said. "I think we will have an overall safer system. It will be more reliable, people will be more comfortable with it."
