Do you have any proof of this, or are you just parroting claims that others are making?
To parrot other people’s claims I would have needed to read them first. So this is my own well informed speculation. I have worked with CO2 thrust and remote controlled cars in my hobby pursuits. This is the simplest way to achieve what was demonstrated.
It can’t be CO2 because they said it refills itself.
That wasn't what was demonstrated, so therefore it doesn't exist. With the past dishonest publicity stunts done before, Tesla has earned this extra level of cynicism.

"They said it refills itself" and you believe their word because it's been so reliable?
What's incredible is how Elon lives rent free in your head
