It's not a new idea, eg: http://bldgblog.blogspot.co.uk/2006/01/sky-tunnels-of-toronto.html (the comments there are jazz)
Of all the transport systems you could put on an elevated path, bicycles might be the best because they are the lightest, so construction would be cheaper than that to carry heavy trains or cars.
I've daydreamed this before, with direction-segregated tubes and vents that adapt to the wind, channelling it in and out of the tube so that it's always a tail wind. I think the insides of the tubes would have to be quite smooth to preserve the air flow. Cylindrical tubes work quite well for bikes because you can lean into the corners better than with straight sides. I'm not sure how safe it would be though: Imagine a crash in a tube full of rush-hour cyclists doing 20 or better, or think of the poor sight-lines as a narrow tube bends round corners...
One things for sure though - i don't trust the man who gave us the superhighways to do it well.
