What distance did you actually see it "drive"? There is no evidence that the car shaped object was anything but a lightweight shell using compressed air to levitate and do tricks like any modern day drone can do.
Here's an RC car that can drive on the ceiling: https://www.youtube.com/shorts/uR_mNcRlNsA
Here's the evidence: https://youtu.be/_lq-DpCE9rU?si=DF8YVr5AB35pKN4i&t=924
The car being filmed and the car that did the stunts are not necessarily the same. See this image for what seems to be an empty husk of the car that actually "flew": https://imgur.com/a/uH9qCxr
that's not the rocket version that can hop, that's the thruster version. the jumping car has a tank instead of a passenger seat
That is clearly not the same car considering you can see the car they are talking about off to the right in the distance (it, rather suspiciously, never leaves the curved vertical track area).
You fell for Elon's three-cup monte.

There's an obvious tradeoff between range and "flight" time, but if you ask your favorite AI it will do some napkin math for you that shows a 4 cold gas thruster system with a 3 foot diameter COPV (at pressures attainable by an onboard compressor) could hover a ~4000 lbs vehicle for a few seconds.
Ask the AI the energy cost of filling such tanks and deduce that from the max range, see what's left after compressing air like that
It has a small solar panel between the lambo doors for providing the electricity needed for the gas compressor /s
Well, Elon said the final prod car would be lighter; whether or not they achieve that goal, the strong implication: the car has a battery and power train in it. Also, we saw it drive up the first part of the ramp without any air seeming to come out the back, and reverse down slowly; there don't seem to be forward facing fans/jets from the looks of the air coming out. I'd say Occam's razor is that the car has a full electric system in it.
I don't doubt it's got an electric system in it. I doubt it's got a battery sized for anything beyond that demo, a sufficiently rigid frame for road use, a reasonable steering and suspension system, etc.
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.
Do you know what a race car is? A race car is a car with, "anything and everything that wasn't necessary for that [Race] was removed to trim enough weight to make the [Race] 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?

I can move my gas powered car that far if I leave it in gear and run it with the starter. Is my car electric?
