Windshield wiper mechanism design defect: In rain and slushy snow my passenger side (ps) window consistently remains clearer than the driver's side (ds). There is a water streak (or ice streak) following the ds wiper at eye level that changing wipers or wiper pressure (bending the arm) won't fix. I've determined this is because the wipers start down to the right and swing up to the left. The ds wiper picks up water and leaves it vertically to the left where it can blow away. The ps wiper leaves a vertical deposit in the ds. The ds wiper than sweeps that down where it cannot be blown off readily. In rain, this puddle gets sucked up behind the ds wiper leaving a trail of water at eye level. Now think snowballs: In snow, the ds wiper compacts this deposit into a pile of ice at the ds windshield bottom. This buildup lifts the wiper and also leaves a clump of ice on it that then leaves a streak of un-wiped snow, again at eye level. Eventually in snow this buildup will spread and cover the whole ds tempting the driver to drive while looking through the ps, until a safe place can be found to exit and manually scrape the windshield. In a recent blizzard on a lonely rural interstate I was in, all drivers had this problem and stopping in whiteout conditions was very dangerous with many vehicles spun out or jackknifed or stuck in the ditch or colliding. This problem can be greatly improved if not completely eliminated by reversing the swing of the wipers. I can't see why this wouldn't work as the only difference seems to be cleaning the upper left of the ds which isn't needed for proper driving and usually has an oil change sticker anyway. This seems to be a problem with all american cars. Do british cars reverse the direction? I file this complaint and form this conclusion from my extensive experience as a forensic engineer.
