It is interesting that this
It is interesting that this is the part that you remember about the unveiling of the Cybertruck. Elon Musk definitely stretches the envelope of what is possible in cars, building a family sedan, crossover, and now truck that are quicker than many supercars. Some features like the Model X's Falcon wing doors are interesting, but often most people would choose a normal door and avoid the complexity and cost if asked about the unusual feature. Similarly Tesla models feature a HEPA filter sold as “Bioweapon Defense Mode.” And even though it might have great practicality for people with allergies, most people can do without the feature just fine. Similarly most of us are not billionaires or drug dealers who worry about needing bulletproof glass for armed attacks in our cars and trucks. I agree that they really should have tested the windows with exactly the same method that they used for the public demo BEFORE the public unveiling, but otherwise this is a small footnote in a rather dramatic EV truck unveiling. Since the Cybertruck is still some time before production they have a lot of time to work out the flaws in the "bulletproof" glass. As far as I know this feature is not commonly available on most other cars and trucks sold in the U.S. so it's not like Rivian (or Ford) has better bulletproof glass. I'm sure that limousines have superior bomb-proofing and better bulletproof glass fitted as an option, but I would also bet that the special glass option on the limousines cost more than the whole Cybertruck does.
