I really like the look of the "rest of the world" I-MiEV with the single windshield wiper system. I don't like the passenger side wiper (as one member described it as looking like Ultra-man). It also causes a problem with the single washer nozzle on the drivers side. It seems to take most of the fluid away before the drivers side wiper gets any use out of it. So, I got the longest single blade I could find at the local auto supply which was a 28" blade, installed it on the drivers side and took the passenger side wiper blade and arm off completely. I like the look and as far as visibility in the rain, it seems to work just fine. The washer fluid cleans the windshield better now. If I can find one that is longer a 30" blade will work also and possibly a 32" would still clear the top of the windshield. The drivers side blade is driven by the motor and linkage first and the passenger blade is driven off the drivers blade. Therefore, it will provide no more (likely less) strain on the wiper system then the original dual blade system.
