Furthermore they have an incentive to lobby for legislation to forbid aftermarket hardware/software, likely in the name of "public safety", but really just sales figures. Electric cars generally have fewer parts that wear over time, so car makers really have to up the planned obsolescence game if, after a major battery breakthrough that allows for more range/lifespan than you need, they still want to be selling the same amount of cars year over year. Can't wait for someone to come up with a full aftermarket car firmware that would let you run everything on it, circumvent restrictions, and disable telemetry.
