Until some open standards are made for car computerization, it will continue to be used as a tool to keep you as a consumer dependent on the company’s good will and certified technicians. It is so much easier to lock a silly little consumer out of a digital system with closed source and obfuscation than a mechanical one, if both systems have a way to be serviced. When this status quo changes, I will finally give up my old 20+ year old cars. As of now, they are reliable as long as I keep up with their routine maintenance, and they dont track me, monitor me, or lock me out when i need to get something changed or modified. - gen Z system admin
