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…
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 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.
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.
