I agree that the main concern should be delivering cars but production delays are solvable while he is still raising money. As soon as he takes his foot off the pedal then their ability to raise money will be much harder than it is while he is announcing new stuff and increasing their risk of going under.

Worst case scenario with his current strategy: they run out of money and an acquirer buys them for the cost of their debt and gets a company with a fully fleshed out product roadmap and some solvable production issues (and no need to solve those issues quickly).

Drop the new product roadmap and focus on production: the going under acquisition is less attractive as they would be acquiring a company with a limited product roadmap and a load of production issues.

He is showing that the future is going to be so amazing that it is worth pouring money into Tesla.
