Picture yourself in the drivers seat of a car, windshield wipers on. The left blade, just forward of your left shoulder wipes an arc of 90 degrees from laying down on the right to straight up. The right blade, mounted in the center of the windshield, wipes an arc of ~120 degrees from laying down on the right to ~45 degrees within the driver’s side wiper arc.
The right wiper sweeps all of its water into the driver’s line of sight. The effect the driver sees is rain, wipe clean, water splashed onto windshield, wipe clean, rain, wipe clean, water splashed onto windshield…
Turn the wipers on high and the splashing is compounded almost completely obscuring the driver’s vision between wipes of the driver’s side wiper.
Why not move the wipers so that the driver’s side wiper is the one that has a ~120 degree arc and water is never splashed into the driver’s line of sight?
The only drawback I can see is that a portion of the driver’s side, the upper left, will not be wiped clean. But how can reducing the area of the driver’s vision be worse than reducing the amount time the driver can see to almost nothing?
