Very impressive prototype. Certainly an attempt to disrupt a specific segment of the car industry - "race cars", or "sports cars", or whatever you want to call it.

A few considerations, just my own thoughts.

1) I would bet that the actual car shown in the demo weights less than what will eventually be sold to the public. I am not an expert, but the way in which the car reacted to the air boosts suggests a relatively "lightweight" vehicle. Plus, I would imagine perhaps a smaller battery (again, for demo purposes).

2) It is a nice "exercise" as a game, or an expensive hobby for billionaires. I doubt, as Elon hinted, that using these thrusters will be allowed on public roads. Perhaps just on circuits?

3) Overall, Elon said that Tesla's strategy will no longer be about cars, but about robots and AI, and then proceeds to show a car that will cost billions to develop, and might not be the commercial success that justifies the investment.

4) Twitter (now X), Tesla, SpaceX... things are moving, tricks are being shown, and who knows, perhaps next year everything will be merged under ElonX, and he will finally be happy.
