They need to keep lane availability up to date - lanes get closed for repair or realignment sometimes and it’d suck to rear-end an 18 ton grader because you don’t have current DOT info…

Anybody relying on lane-keeping assistance to prevent from slamming into the back of big yellow construction vehicle is doing it wrong, and we should be thankful they didn't hit something else with more victims.

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.

I didn't know that. I assumed it was sensor-based. How up-to-date can that really be? That sounds pretty crazy.

It does say lane "keeping" not lane "changing". I assume it's the safety feature to remain in the lane.

I've seen lanes on highways that abruptly end with zero markings or signs - the concrete barriers just force you into the other lane just as you realize what's going on.

		I would have doubted this had I not experienced it myself on my way home from a movie last night. Not even a construction sign! Let alone something reflective.
