IMO Tesla reached "maturity" with two issues:

- It was so incredibly overvalued before being mature, that once it actually started to deliver on some promises its price shot up even further from where it should be.

- It reached "maturity" too late. Other car makers have caught up. Consumers can buy a Ford F-150 Lightning, an Rivian R1T or a GMC Hummer EV today, but not a Cybertruck. Kia, Nissan, Mini, Porsche, Audi, etc have great EV offerings. Tesla isn't even the biggest seller of electric cars in the world anymore (it's BYD, 354k sales vs Tesla's 254k)[1]
