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.
