I got a rock chip crack in my windshield about a year ago. It wasn't reparable. I didn't repair it because I knew it would just get more chips and I could live with the crack. The original crack spread. Today I got another chip which I'm sure will turn into another crack. I'll replace it soon.
My minor suggestion: Instead of me spending $1,500 every year or two for a new windshiled (plus re-tinting), why can't we just spend $3,500 or whatever for some of that Tesla Semi impact resistant glass for the windshield? Please, Tesla, take my money.
