Keep in mind the chips that car makers were having trouble getting were primarily for their worthless, poorly designed, tochscreen-nightamre "infotainment" systems. Most of the chips in a car are automotive grade jelly beans that are not made on a modern process, so they were mostly unaffected by the surge in demand for PC parts. They always had the option to just use a normal radio as standard instead, but then they couldn't charge you $3k for a low-res resistive touchscreen with less functionality than an iPod Touch.
But some things to keep in mind about Tesla:
- The driving systems of their cars are completely dependent on AMD/Nvidia chips. They can't even show the speedometer without a high powered GPU.
- Tesla's value is as a tech company, not an auto manufacturer. The big car manufacturers usually make more cars in a year than Tesla has made in their entire existence. Tesla's high market cap is based on IP, not their ability to make cars.
- Tesla was absolutely affected by the shortage (see the repeatedly delayed CYBERTRUCK), they just needed FAR fewer chips due to their relatively low volume production.
- Tesla is hitting their "2 year threshold" for their Chinese factories, meaning all IP that they've built in that country has been reverse engineered/stolen, and soon will be openly available in knockoff products - probably by the end of this year.
