Looking it up, the doors are 1.8mm steel. At a 90 degree angle that’s enough to stop underpowered 9mm rounds reliably. It will stop most normal rounds fired at it, and especially start letting a lot through in areas with repeated stress. The second you hot load a round, use a heavy projectile or any kind of round with more potential than standard FMJ it’s all going through.
And that has to be the right kind of steel too. Which is more expensive. So yeah I’m pretty sure they used underpowered rounds at the very least to create this visual.
1/4 inch is for armor that you want to be able trust and keep using. 3/16 inch or 4 mm will be the bare minimum for one time use. The Cyber truck is 1.8 mm.

He also got a door given to him specifically to test. Which is suspect too.
