Ah sorry, I was conflating two technologies (which are basically the same in my model). "Available LaneSense® Lane Departure Warning with Lane Keep Assist alerts you with visual and audible warnings during unintentional lane drifts and corrects your vehicle back into its lane."
I get a visual (and optional audio -- which I disabled) warning and a little steering wheel resistance to bring it back into the middle of the lane.
While I'm not sure what the minimum speed for adaptive cruise control is, but I use it in freeway stop & go traffic often.
It sure does get them a lot of attention though! My Jeep Cherokee has lane assist, adaptive cruise control, auto-parking, and crash detection (emergency braking) but they don’t get all this press about it.
When someone recommended it to me last summer, I was hesitant to be yet another content creator for yet another platform. Then I saw it was run by science foundations! Signed up immediately. It’s been fun in Colorado to learn plants that I see on hikes.
