Lane Departure Systems

Have the lane departure warning system on our Edge. It's not horribly intrusive but will occasionally get confused in construction zones where the lines are overlapped. Does not work very well in the rain at night as I guess it has trouble seeing the lines, or maybe there is just too much water on the front camera lens. I can set the correction "strength" to low or high to control how much force it applies to the steering wheel. Even on high it is not difficult to overpower it. One benefit, it has forced me to be more diligent about using my turn signal when I change lanes.
Would not ever consider adding it to the MH. If it came as standard equipment, I would want a way to easily turn it off. There are too many instances where I need to "borrow" a bit of the other lane to make a turn. Only see LDW being useful in the MH for interstate driving.
