Standards are for transparency and strength, which is pretty much what I said. No mention of a standard for thickness, which is what you said we should measure. Thanks for driving my point home.Federal Motor Vehicle SafetyStandard 205 (or FMVSS 205 for short) addresses windshieldglazing standards. In simple terms, this piece of regulation sets very precise standards for auto glass transparency and strength.
Federal gov is involved with every aspect of your vehicle, to include windshield.
Sucks but lessons learned over the years has enabled big brother to be specific on glass design and strength. Granted, some will cheat the system. Aka vw and their emissions scandal....again, i stick to my orginal quote, read the regulation, go measure the thickness, compare, and if measurements are off, you have a legendary legal case worth millions. My take is now 20%.
