Talking about snow... When it is below freezing and snowing quite often there actually should be no requirement to wipe at all. The key thing is to _not_ have warm air blowing to your windshield and the snow would never hit the glass due to air moving it away while driving. And if the glass is cold and you stop, the snow will blow away automatically again when you start to move.

I think I am just personally used to not keeping the glass ultra clean (and wiping almost a dry window all the time) and found the automatic sensor too sensitive even with the lowest setting.

I also would not want a rear glass sensor since the water you get on the rear glass is always dirty. If it is raining hard, the sensor might work fine from dirt perspective. But if the road is just wet or raining a little, the wiper would wipe the glass with quite a bit of dirt on it and the glass might end up with scratches and premature wear. I prefer using the rear manually with enough water every time.

That is also the reason why I don't like an automated rear wiper activation when reverse gear is activated and front wipers are active. You might wipe a glass with an inch of dirt on it without any water (I hope my BMW does not have this functionality).

But maybe that's just me.
