LOL, I’m not the one who apparently can’t comprehend the difference between a couple of unrelated microcontrollers adjusting air/fuel ratios and doing anti-lock brakes and such, and a full-blown integrated infotainment unit with CAN-BUS connecting everything and infected with DRM such that if you try to replace any part of it the system locks up until the dealer or some other manufacturer-“authorized” tech supplies the right encryption key to ‘allow’ you to use it again.

Your ridiculous attempt to conflate those wildly disparate things is your defect, not mine.
