How do you think right-to-repair intersects with cars?

An obvious thing may be to say the software must be published or the spec released, but we've had computers in cars since the 80s. It seems like a tall task but people can and do reverse engineer entire ECU systems (See Trionic Tuning)

Another seemingly very obvious one - requiring manufacturers to publish specifications regarding ALL OBD interface options. Of course this immediately runs into trouble. Saab for example gated features of the security system to prevent key reprogramming, swapping of certain components without a dial out to the internet using specific saab software that runs on a laptop and interfaces.
