Don,
I don't think the spoilers on the Nationwide cars are as high as the ones on the Cup cars were. Atone time there was even talk of making them out of clear plexiglass so they could see through them but that wouldn't work either. Just another of the many rumors that abound when changes are made I would guess.And I would think the drivers height might also play into this as a taller person might be able to look over the wing easier than a shorter one. I have heard some drivers say they don't have much trouble seeing out the back and others say they have problems. Not sure what the answer to that would be, but they all seem to agree the wing does create lift.
