I'm sure it was being run over that did it in. The only other instance of a windshield cracking that I've been told about, was it being stored outside in the sun in FL year round. 4 years and UV had turned it a yellowish color and made it brittle. Mine are always stored inside, and none of them have done anything be get scuffed up from running into limbs, logs, or being bent on purpose to clear obstacles. You bending it over the GoPro mount isn't going to hurt anything, just trailer tires. LOL I'd be happy to fix it for you if you decide that's something you'd prefer. No charge other than shipping.
