On car design – Why can’t they get wipers right?

Car design must be a complex and impressive process to follow from inception to delivery. One component that will forever mystify me is how automotive designers manage to ensure that the driver side window wiper is always the one that works the worst?

I have owned three cars so far, and driven in heavens knows how many more, and for some unfathomable reason, the driver side wiper is the one that almost always starts streaking, leaving swathes of the windshield untouched, or fails to scrape slush off first. I have to wonder: has it ever occurred to designers that they could switch the orientation of the wiper arms? Perhaps they could mirror them horizontally so that rather than wiping from right to left, they wipe from left to right? There certainly were the crazy top-down wipers on minivans in the 80’s. I wonder why they went away?
