I've never had a point where it is dangerous. It vibrates the steering wheel and that's it. Even on the autobahn's 2.20m wide roadwork left lanes it works good/not bad enough I just leave it on. Lane keeping is not mandatory, only a warning system.

I had it behave dangerously on a VW Atlas I rented, driving south out of Atlanta. A section of 85 has those half black, half white high-contrast stripes, and I had to firmly grip the wheel for the entire section because the lane keeping system was constantly trying to correct.

I guess it depends on the maker. For my car it nudges the wheel back into the lane in addition to vibrating.

Yep, it does, our VW also nudges back to the lane. The annoying thing is that you can only disable it by stepping through two pages on the on-board screen, though I think many newer models just have a button on the steering wheel to toggle it.

I had lane keeping “assist” in a Subaru Forrester rental car almost kill me and my family by trying to push us into the path of a very large truck last year.
