this has been on my mind alot lately is the idea of a rear windshield wiper. I think it would be great, get to removes water that just hangs on the window along with snow and all that fun stuff that can obscure vision. I dont' know if you can drill a hole in the glass, i haven't looked into that to see if it can be done. I'm not sure as to what kind of wiper/motor to use yet, I was thinking about a 240SX or something that is about the same size. Any input??
