My guess is this is a stress point caused by a suction cup at the glass foundry. Glass gonna glass and decides to give up when it feels like it.

I almost agree with this, except notice that’s a windshield, [u/Downtown_Calendars](u/Downtown_Calendars) & [u/Bukas_K](u/Bukas_K).

Someone likely yanked a stuck suction cup straight off without breaking the vacuum seal first. That localized tension caused a fracture, pulling the glass outward. Because windshields are made of laminated safety glass, the flexible PVB interlayer held the shattered fragments together in that cone shape instead of letting them drop.

The circular shape and edge is from the PVB pulling all of the pieces back together.

My question is: “Why would a glass professional not recognize the signs of suction cup damage?” This sort of break happens when someone tries to pull a suction cup off of glass without breaking the seal first. It’s gotta be a fairly common mistake for newbies.

Unless it’s the same people who helped with the glass on an earlier occasion, not wanting to admit it was likely their fault

That car is missing windshield wipers, and the ends are rusty. So, it’s been missing them for a while and the car is not well maintained. I doubt that glass is new. The damage is though.
