I disabled lane departure warning for my driver profile. It was annoying in city driving where the road is shared using rules that do not line up with lane painting. When you flow with the traffic there is no danger in crossing a lane marker so I shut it off.
Same here. I wanted to like it. I wanted to use it. But it annoyed the hell out of me on narrow two lane roads with "false" alarms. BTW, the lane departure warning on my previous 7 series BMW was just as annoying and got turned off too.
