one of my ride has the adaptive light + washer. i find the washer is not needed here. infact, dirty the car more. cos when you spray it on the headlamp, the dirt will trickle to the sides, dirtying the other side panels of your car.
the adaptive thingy, good to have but not a must. There is this another feature which i find it to be more useful than the adaptive light. when you turn your car to either left or right, there is another side light that will illuminate the area which you are turning to, i find it to be more useful than the adaptive.
so, not really a loss if you don't have it in your car (referring to adaptive and washer).
