Its probably a standard Musk project. Show futuristic marketing pictures/videos of round pod-style futuristic vehicles to billionaire oligarchs and clueless politicians with a buzzword salad, until the hype brings in investors. Interest in his companies goes up, the imaginary price of the company goes up, his imaginary gold pile gets bigger.

Then pocket the money and fail miserably delivering even a fraction of the promised things.

The tunnel in Las Vegas, Hyperloop, Cybertruck, Robotaxi (still in progress afaik) Tiny House, the electric freight truck (I don't remember its name), the various Mars projects just to name a few.
