One of my bigger gripes about the new Volvos. The computer controls everything! And only the dealer can change the "options".
When the rear window is covered in dust, you want to wait until it is wet before turning on the rear wiper so that you don't scratch the rear window. With the cover above the rear window, it may not get wet even though the windshield needs wipers.
Just like rain sensing wipers. I know when it is raining, and there are times in the Midwest when there are so many dead bugs on the windshield you don't want the wipers to come on until the little buggers are soaked and come off easily. What happens when you put RainX on the windshield and you are traveling on the Interstate, the rain rolls off and visibility is better than when the wipers are on? Stupid options! Poor design.
