Uhnn... so do you think the glass in the unveiling was the same from previous test?
Remamber they did in two windows.
By the way, the video of the VW glass test was not using a Tesla "metals glass"
but a usual VW glass, if we read the video description:
"A demonstration intended to show the strength of the windows on Tesla's first pickup truck went wrong when Elon Musk’s team threw a metal ball at them.
I've made the same test
with a normal window and the metal ball didn't even scratch the glass!
How hard is a normal window compared to the Tesla Cybertruck window?
In this video, I've tested how hard is a lateral window from a VW Golf.
In the first test, I threw in the glass with a 0.5kg metal ball - test passed successfully.
In the second test, I hit the window with a 1.25 kg hammer - test passed successfully.
In the last test, I hit the window with a 4 kg hammer and the window breaks instantly.
After I broke the normal window I decided to make the new window indestructible adding one the exterior a 4mil Safety film from Armolan and on the interior a 1.5mil Film Hp Eldorado from Armolan this is how you make an Armor Glass.
The result was awsome the window didn't break after I hit him repeatedly with a 4 kg hammer and a 0.5kg metal ball.
I found out that the side windows are really hard to break.
The metal ball didn't even scratch the glass, my window faced a 4 kg hammer."
If the hammer in the video are real... I have my doubts. Anyway if the hammer had sharp head it would broke the glass.
I saw people with cars usings films against vandamism, for windows, and the windows even so use to crack when hit with small hammers, despite hold, like a bullet proof window when get shot with bullets.
I'm not sure about micro tension bulid up, but I know glass can have micro invisible cracks that accumulate over time. I oncesaw a glass cup of juice explode on table, when I waxmixing it with a small long spoom to dissolve sweetner.

If they hadn't run that test before the unveiling the windows would have coped well.
My parents used to have a long narrow low table of which the top was a sheet of glass supported by the corners. It was more than a meter long and at least 10 mm thick and quite heavy. It has taken a lot of abuse over the years, including me as a toddler using it as a trampoline. When my parents pulled me away they marveled that the glass did not break as they saw it bend down deep.
Then one day someone dropped a tiny fragile worked crystal liquor glass on it from maybe 10 cm above its surface. An enormous bang as it shattered in hundreds of flints. And right in the middle of the carnage was the liquor glass, unharmed...
