I've actually found the lane keeping in my Mitsubishi to be basically flawless when operating. Potholes and the like don't seem to give it any issues at all.
It does lose track of the lanes and periodically disable if the lines are faded or absent for more than a few meters, but at least then it just switches to normal steering and doesn't swerve me into traffic or anything.
The way the quizzical "huh" is sometimes pronounced is close perhaps? I don't know if I'd call that an English word though.
