This is the only feature that's so far annoyed me about the F30. Manually activated automatic wipers? That's bollocks. I don't care what crappy excuses you want to justify it but manually activated automatic anything isn't automatic and is, therefore, retarded. Icy? The car has a thermometer - disable it in software. Carwash? Well if you go through carwashes with your engine running then you're a numskull. My last dozen cars have had auto wipers and I've never had them activate automatically in either ice or a carwash. Besides, who takes cars through carwashes anyway? Don't you people care about paint?
Any which was you skin it, it's a stupid, stupid feature and unique in any cars I've driven ergo ... BMW has got it wrong.
