Lane assist isn’t lane centering, it doesn’t keep your car in the middle of the lane, and just applies a small steering input if you drift out of lane.

The systems tend to be quite noisy and annoying, and also won’t keep you in lane by themselves, and they normally result in the car “ping-ponging” between the lane markers until the system gives up and stops applying input. There is nothing about these systems that would cause to actual rely on them, they’re simply too annoying and uncomfortable.

That's like saying that ABS gives you a false sense of security because you can stop in situations you wouldn't be able to otherwise - but obviously the solution isn't to get rid of ABS, it's to learn where the limit of the system is.
