Sounds like you're comparing apples and oranges there. The technology involved in space travel and the technology involved in clean glass aren't the same. (In fact, I'd imagine the glass on a space shuttle will also have the same problems!)You would think as we can send men to the moon and with all the amazing technology around today that such a trivial thing like dirty windscreens would have been easily fixed by now.
I imagine it's simply that the will isn't there, basically the designers feel drivers will manage with what they've got.
Take your standard estate car - it has all sorts of technology in it to do with the safe running of the vehicle, but at the end of the day, the only way you can really clean windscreen glass is by wiping it, preferably thoroughly with a brush. I don't think any amount of technology can stop bugs splatting on the front of a moving vehicle.
