Fascinating situation.
Tesla is at most worth 1/10 of it's current valuation. Given its huge legal liabilities ahead from selling 'self-driving cars' for the past 10 years, it's probably closer to 0.
The crazy valuation is 100% dependent on Musk staying.
Musk net worth is very much dependent on Tesla too - if Tesla crashes, so does his fortune (yes, SpaceX is valued at a crazy number too, but it's not liquid and doesn't bring any real cashflow, at least not yet. And he used Tesla shares as collateral worth billions).
Tesla board member are all Musk buddies and have 0 agency.
Telsa shareholders know perfectly well that the stock tanks if he's gone.
Yeah, in short - everybody knows it doesn't make any sense anymore, including Musk and Tesla, but they have to keep the ball rolling, because they are all in it together. Every involved party looses money if he quits. If he stays they can get some more years of dumping their stock on naive 'investors' that are getting duped by the massive propaganda operation run on Twitter.
PS. Robotaxi will serve 50% of US population before the end of the year according to Tesla & Musk /s
