When my RG flipped into a ditch, the clearview broke into several pieces but did not shatter.

I have not read all 3 pages, but I have worked as an engineer in a plastics factory in my life, and worked extensively with polycarbonate, which is better known by the trade name LEXAN
If the material was properly handled, meaning dried before injection and no water in the manufacturing process, the stuff is bullet resistant.
How we verified that parts we manufactured out of engineered structural foam polycarbonate were manufactured with the proper blowing agent and properly dried, (and these parts weighed 200 ounces) was to either hit them with a hammer, and I mean effn hit them hard, or we would hold them over our head and throw them on the poured concrete floor. If it didn't shatter it was good to go!
Acrylic windshields can not be cleaned with anything that has ammonia in it, where polycarbonates can.
you can buff scratches out of it too

I've ridden various bikes since the late 60s with windshields. Some have come with the bike, others I have fitted as after-market accessories. I have almost half a million miles up, the majority behind a windshield and I have been hit by a wide variety of stuff off the road, but none have ever suffered anything more than a scratch.
