I have regularly been effusive about General Motors’ Super Cruise. By geofencing the combination of adaptive cruise control and lane keeping so that it will only engage on divided-lane highways and topping that with a gaze-tracking driver-monitoring system that only allows Super Cruise to function when drivers have their eyes on the road ahead, it works extremely well and within a tight operational design domain that should preclude any chance of encountering a parked car.
After trying it out in the Cadillac CT6 in 2018, I was so impressed I echoed Alex Roy and called on GM to make Super Cruise available in as many models as possible, as soon as possible. GM is slowly doing this. Even Consumer Reports was impressed. But in all that time, I guess I never read the fine print.
