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.
Check out Tech Gear Lab and Outdoor Gear Lab. They’re based in Tahoe and the company purchases every single item they test. When they’re done with testing, they often put the gear up for raffles locally to support mountain bike trails and outdoor non-profits. The folks who run it are all really great people.
