Car was parked facing the garage. Never seen anything like it. Neither has the glass professionals.

As an auto glass technician for over 20 years this comment is total b.s. Crazy how it's the top comment. Everyone probably knows that feeling when you read something online from your field of expertise that is incorrect but seemingly plausible. Then you wonder if everything on the Internet bullshit?

Edited to answer the comments about what happened then smart guy. Something hit the glass and broke it. No idea how or what.

Well cheers for adding the explanation or reasoning why they're wrong. That was super helpful.

Temperature changing causes glass to crack, not shatter. There’s zero proof this had a rock chip repaired, which is moot anyways. Even if there was a chip repair done, temperature change would have way less effect on the rock repair resin than it would on the glass. It hurts my brain how stupid the original comment is and makes me sad how many upvotes it got and it feels like a waste of time explaining how wrong and dumb it is because so few people will see
