Automotive CPU, MPU, ECU, etc. are often designed using in ASICs (Application Specific Integrated Circuits) and nowadays FPGAs (Field Gate Programmable Arrays). The software is not served up by a drive, or kept on a flashable EEPROM, it is literally built into the silicon. Or in the case of an FPGA it is mapped onto an all purpose Gate Array - essentially hardware, not software. The OS is real time, or deterministic, so there is less glitchiness and no need for fancy GUIs and such (there are certainly higher level GUIs like Teslas, but at the functional level (not the wants and needs of the operator level) of running the car, a deterministic control system is very attractive.).
This is definitely the better way to operate equipment. It may require the original the development system to reprogram it. Or it can only be reprogrammed by replacing chips and boards - meaning it is very unlikely a DIYer will have the ability to hack it. Far more likely to strip off the salvaged control system and use more basic systems. Hard to see how a salvaged Tesla, with all its controls removed and DIY ones installed would be a satisfactory result. The OEM controls are the result of many thousands of hours of programming by some of the best minds silicon valley has to offer. The reality is, cars have achieved levels of sophistication and function with the Tesla,, and high end ICE, that scratch built alternatives night not be very popular.
