Since the topic here is the teardown, thought we were discussing the mechanical side of it. As of the Linux kernel there are actually a few people who have very, very thorough understanding of near every design aspect there, even if they didn't memorize every line of code. Linus Torvalds is certainly one.

That's excessive for automotive software, however; you do some device drivers here and there but ain't going to modify the memory allocator or process scheduler. How much detail Musk keeps on to here is open to speculation. On my part, I can say the industrial products I developed I understand really well. Starting from where and why ejector pins on diecasting molds go, the particular conductor plate used for spot welding, wire gage in the cable bundles, through kernel drivers, FPGA programming, EMC compliance issues in PCB layout to how many units fit on a euro pallet.. and am no Elon Musk. Don't sell your ability short.
