Is Tesla's Cybertruck bulletproof?

Is Tesla's Cybertruck stainless steel alloy bulletproof? According to Elon Musk, his windows are even though he couldn't prove it during the Cybertruck's presentation. A Youtuber tested the resistance of the armor to live bullets.

Tesla has not confirmed that the Cybertruck's steel is bulletproof, but still said "if there was anything better, we would use it" when talking about the alloy. . In fact, Elon Musk's company has kept its word as the current stainless steel will be replaced by a 304L alloy. This is the same alloy used on SpaceX's new Starship prototype. During the Cybertruck's presentation, Elon Musk had only explained that the vehicle's windows were bulletproof. As you already know, this demonstration was a total failure.

The stainless steel plate has been fired by several calibers. Youtuber Bob Edwards tested the 9mm caliber and a rifle caliber, but he did not say which one specifically. As you can see from the video, a 9mm bullet does not pass through the plate while the rifle bullet does so easily.

In addition to bullet resistance, Bob Edwards tested resistance to scratches, especially those caused by car keys. The scratches are almost imperceptible. However, when he tries the experiment with a knife, the scratches are rather noticeable. Finally, the hammer and pickaxe test revealed that the impact of these two tools is also capable of damaging the steel alloy.
