An interesting thing is, my wife hates LKA. She always turns it off, and if she forgets to, it'll soon do its thing, and she'll shout and swear at it, and I'll turn it off as she drives.
Whereas when I drive, I don't turn it off, and I think it's only nudged me twice in the three months we've had the car. And it's never bothered me -- once it was "oh yeah, I drifted out of lane there" and the other it was "I understand why it thought that, and I can override it".
I think it must be a very small difference in the way we position the car. I don't see anything wrong with where she puts it, and I don't perceive that she fails to indicate or anything like that. But it nudges her much more often than it does me.
