It wouldn't be the first time Musk demoed something and promised something and then never ships.
Here's an RC car that can drive on the ceiling: https://www.youtube.com/shorts/uR_mNcRlNsA
You fell for Elon's three-cup monte.
My general assumption is that anything and everything that wasn't necessary for that demo was removed to trim enough weight to make the demo possible.
Tesla's website literally says the Rocket version is "Not approved for public road use." And has "Seating for one." Any battery that can perform that demo can certainly power basic driving. You're accusing them of deception when every modification you describe is plainly stated on their website. (E.g. It's drive-by-wire, and the seats are modeled chassis elements. Yes, it's wildly minimal.)
The expectation that a vehicle that did a literal standing barrel roll (even if only a single time) be functionally equivalent to a Toyota Camry is madness to me. The much more interesting question is what type of localization system in 3D space were they running?
What we saw was impressive, but it’s a trick. The car’s tanks are surely empty after this, and now you have a loud compressor filling them up for minutes. You can’t use those thrusters near people and cars cause you’re at risk of getting them in trouble.
It’s part of a long history of useless tech in supercars. Impressive, but useless.
I'm not saying its impossible but it seems pretty naive to just assume on face value
For what it’s worth, my $600 hunting rifle will go clean through both sides of any bulletproof vest, and it’s nothing special.
For everything that is bulletproof, there is always a calibre of projectile that will go through it.
