BTW, Tesla doesn't make their FSD boards- they don't own a chip or motherboard factory, they pay another company to do that based on their design. So does Nvidia. Same-same.
Yes. That theory is beyond pie in the sky. I know people working on the infotainment systems for big OEMs (Daimler, BMW) and the designs and production are auctioned off with the lowest bidder winning it most of the time. They use off the shelf processors that are available in volume and have very low margins since they're basically a commodity at this point. Even Nvidia has some of those as well.
The correlation between what people read in the media about Nvidia's crazy gross margins and what gets used in cars now is basically non existent.
