I have several GM cars, 2 Corvettes and I love what you have done with the C7 and Z06. However I have had several cracked windshields from gravel getting tossed up, and this week I got another. Speed limits have risen yet windshields have become very thin and light. Do windshields become brittle; as temperature expansion and perhaps UV stress the glass over time? Do you have any statistics you can share to prove or disprove me? Can you share the process that GM would need to do to get new technology like Lexan windshields past the DOT. Or how hard was it to get rev match past the DOT?

Thank you
