A couple weeks ago, I was driving on freeway with no one near me, and I suddenly start to hear what sort of sounds like micro gravel pelting my windshield or even as if there were cracks appearing all over the windshield. I can’t see anything hitting it, nothings actually cracking, and again no one in front of me that could be spitting rocks at me, so I’m confused. It lasts for about 10 seconds then stops. I go about my day. Fast forward to yesterday. Driving on fwy, again no one in front of me for at least 800 ft. All of a sudden, we hear a loud pop, and a dime sized crack appears in the center of my windshield. My wife’s coworker also got an M3 a month ago and also got a crack in her windshield within that month. And I was just telling this story to a friend of mine today who just got his M3 and said he also heard that same debris-hitting-windshield noise for no reason the other day... I drive 120 miles a day every weekday, plus some amount on weekends, and have been doing that much driving for at least the last decade. I have NEVER had a crack on my windshield in all that time. What gives here? Is there a potential quality issue with M3 glass we should be raising to Tesla? Or is this just a totally bizarre coincidence?
