The project started sometime around 2016, so going by Apple’s track record 2024 seems like a possibility. Tesla needs a competition and is slowly turning into a monopoly.
As they say, the market can stay irrational longer than you can stay solvent, so I'm not going to bet against Tesla. However I'd be shocked if Tesla will be a top 5 car manufacturer 10 years from now.
The reality distortion Apple has pulled on its most euphoric apologists is insane.
