What would you improve with modern lorries?

Mirrors .
When will they find a way for mirrors to not get misted up or obscured by moisture falling from the sky .
Clean them in the services , drive a couple of miles up the road in the rain and it’s back to square one , switch the heater elements and all that does is bake it on . Yes you can wipe it going along but not the passenger side .

I’ve always wondered why none of the manufacturers have put wipers and washer jets on the mirrors, you have them on a lot of headlights and unless you’re partaking in the Dakar rally or something I think they’re pretty useless, so why are they not on the mirrors where they’d surely aid safer manoeuvring?
