When we first tested Super Cruise in 2018, the partially automated driver's assist impressed us enough that we wanted to see it rolled out across as much of General Motors' lineup as possible. Seven years later, our attitude toward such driver assists is a little more sober. Drivers are often more confident about such systems than they ought to be, and that's when they even care about such features in the first place.

Nonetheless, Super Cruise stands out as one of the more effective examples of what the industry has awkwardly termed "level 2+" driver assistance systems. In simpler terms, it allows drivers to operate hands-free for extended periods, provided they remain focused on the road. In the case of Super Cruise, this is made possible by an infrared camera that monitors the driver’s gaze, ensuring they are attentive, even if they happen to be wearing sunglasses.

Even better, it's strictly geofenced, designed specifically for use on controlled-access, divided highways.

Despite the somewhat strict "operational device domain," Super Cruise must still manage a diverse array of driving scenarios—ranging from the frigid depths of northern winters to the sweltering heat of southwestern summers—while also accommodating various vehicle setups.

"From the very beginning, our goal with the Super Cruise steering control was to achieve several key objectives—primarily precision, comfort, and instilling confidence," stated Reza Zarringhalam, a software developer at General Motors. "We aimed to ensure that drivers feel at ease while the system takes over the driving responsibilities," he added.

This implies that lane centering must ensure the driver doesn't feel overly close to a neighboring semi-truck. Automated lane changes—triggered either by the driver activating the turn signal or by the vehicle assessing lower traffic conditions—should occur seamlessly. Additionally, it's crucial that the individual in the driver's seat can regain control of the steering effortlessly, without struggling against the system.
