Elon is wrong on this because the back window broke too, also doesn't make sense why that much stress would be sent from the door to the glass and microfracture it to my intuition
It's obvious that the difference between the test and the live failure is the frame that's installed around the window. It's missing in the test, and the window is free to flex and "rubberband", absorbing a lot of energy. Wheras if it were rigidly mounted in a frame, the glass couldn't change shape and it would be much more likely to break.
Also there's the drop test they did where the glass wasn't clamped down tightly and they had to reclamp the vices every time they dropped a ball. The glass would bounce off the stand a few inches when struck.
I've only ever argued this once because when I did some sperg had a female brain understanding of physical objects and I just figured the retards out there aren't worth the effort.
