Tesla, for the most part, is skipping that validation and just shipping cars. The warranty issues from Tesla have been notorious, but their business model is to ship cars as fast as possible and deal with warranty issues later. They were able to side-step much of the chip supply issues by either shipping cars without certain features (no adjustable seats, no USB-C ports, etc.) and also switching to newer 7nm+ parts, like the AMD Ryzen x86 chips that they've started shipping in the past few weeks. Their direct sales model allows them to easily change the price on the website, and so far, they still have unbelievable demand.
