Korean cars manufacturers created now mature brands from scratch. All it took was billions of dollars and a couple decades of time. Can a startup do it? No. Is the market locked up? No as well.

Despite the hype and genuinely great technology and growth it's still nowhere near competitive with the big automotive firms.

So while Tesla has definitely driven innovation here, there are still MAJOR hurdles to them being globally competitive.

Further it took Billions and someone like Elon Musk to be able to get even this far, so in that context if even Musk and tons of government dollars can't get there then it's safe to say nobody can.

Tesla isn't competing with Toyota... They are competing with Porsche and Rolls, etc. Further, they are a mess financially and have not proven to have staying power.
