How about drag coefficient?

It didn't break on stage in isolation. Two broke. Tesla armor glass was already claimed years ago to survive a nuclear blast (Tesla Semi reveal). It seems to be marketing.
There are like five video clips online of the glass withstanding greater impacts. Tough glass is not science fiction. It is well within the capabilities of anybody to take some bullet proof glass or thick poly carb and stick it in the window. So saying that this glass is all marketing doesn’t make any sense. Literally anyone could do it. Many already do. It isn’t a new thing. People get tougher glass installed after market literally all the time.
Elon musk tweeted a joke that Tesla semi glass will withstand a nuclear blast or you get a full refund. It was a joke dude. You are really dumb.
What he actually claimed is that the glass won’t crack if a small rock hits it. The cost of the tougher glass is less than the average cost of downtime caused by cracked windshields. Truckers aren’t allowed to drive with cracks. So in reality there is some really straightforward logic behind the glass.
