Why Musk would spend probably tens of millions of dollars on this prototype which clearly will never be drivable on roads. One explanation is he is a trillionaire and the 14 year old in him thinks it would simply be cool to do it.

I think there is a more rational explanation. Tesla sales have slowed, other companies are catching up, and if it weren't for import issues, Chinese cars would be eating Tesla's breakfast, lunch and dinner. Yet Tesla is trading at a 330 P/E and Musk has to do something to make it seem like Tesla is still light-years ahead of everyone else and just wait, that 330 P/E will be justified any quarter now. Just like shooting a roadster into deep space was just a PR stunt, this is a PR stunt to boost the brand with no actual market relevance.

> other companies are catching up

Catching up? BYD has already surpassed Tesla and looks like the gap is going to continue to grow.

It is because he is very desperate for nerds to think he is cool so he lies and does PR stunts to that end and it works

Absolutely, but an even more likely explanation is that he's going to "acquire" Tesla with Space X and pay a premium (on top of the 330 P/E!). The SEC in this country is completely useless. Sure you can't invest in private companies if you're not an "accredited investor" but Musk is free to scam trillions of dollars.

Is this your first time seeing a concept car?

> One explanation is he is a trillionaire and the 14 year old in him

At this point it's not clear that there's anything other than a 14 year old in him. A greedy, sociopathic 14 year old.
