I think the term has been used for various capabilities over the years.
replyMy friend's 10-year-old Toyota will chirp annoyingly if you drift over a lane line but that's all it does. It doesn't have any ability to steer the car back into the center of the lane. Is that "lane keeping"?
No, that's "lane departure warning"
replyMine has either off, warn, or warn+adjust (but adjustment is very gentle, more of a nudge).
replyI can imagine it can save a life someone dozing off and drifting.
Also great if you are distracted, perhaps by kids in the back or something happening on the side of the road. Mine has chirped at me a few times. It's basically the electronic version of rumble strips.
