They do not have wipers fitted but some are heated(you pays your money etc).
In use the forward motion of the vehicle leaves the camera in an area of dry-ish air.My friend has his mounted in the no plate recess so that gives some protection Mine has a cowl over the top.
My camera has 14LED so in murky conditions you can still see that something is there .You don't need HD quality.
Lets face it in very heavy rain its a job to see forward when overtaking lorries with lots of spray.
I follow your point about width of vehicle but are there many that can see down the sides of the new breed of caravan at 7ft6in wide without extended mirrors ?
