And yet what has it got by sales numbers or IP? And how much does it make per car sold (especially after all the fixes for QC issues that shouldn't make it out of the factory)
You just have to look at various "tech" crashes to see how little "share value" can have in relation to actual value in companies when there has been a charismatic leader who has managed to put on a front.
I saw something earlier that was saying that the various "AI" companies lost nearly $200 billion in value practically over night after a single google report into the value of it or something, meanwhile Twitter was once valued at over 40 billion and is now worth a fraction of that.
I suspect most of the traditional car companies have a lot more of concrete value, including various driver assist tech, let alone actual infrastructure than Tesla, they just don't have a guy who can persuade people that he'll have self driving technology using webcam and laptop within the next 12 months every year for a decade or two.
