@ArchieBAntlers A while ago, car makers decided to turn every car, whether it's driven by combustion or electricity, into a network of computers--and they didn't do it in a robust, reliable, easy to maintain, way, which would have been possible, they decided to do it with all that DRM bullshit designed to make it impossible for people or 3rd party car mechanics to repair, maintain, or modify, anything about their cars. Every car part has a computer inside that needs to talk to all the other computers, and there are cryptographic chips inside those computers to make sure every part was made by the original car manufacturer, that you cannot just buy any standard part on the free market. You cannot even buy an original part from the original car maker and just replace it or have an independent mechanic do it because the new part needs to be entered into the local database of your car's main computer system, and in order to do that, you need the cryptographic keys that car manufacturers don't just hand out to anybody, just to their authorised partners.
