My assumption would be that lane keeping would be about staying in the lines ahead of you, not knowing which lanes are available on the route. Available lanes can change in real-time due to all kinds of reasons.

I think the term has been used for various capabilities over the years.

My 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"

Mine has either off, warn, or warn+adjust (but adjustment is very gentle, more of a nudge).

I 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.
