Does the fact that most of the code in your car is autogenerated from tools like Modelica change your view on how likely this can/should be opened?

That is, the 'model' is the truth and the IP. The generated code is spaghetti, the vendors components are black boxes, and their 'code' is nothing more than another locked subsystem in the model.

Let's say in an ideal world, these mission critical systems must be opened - what do you propose everyone's business model should be? If everyone must see each others models... where is the free market competitive advantage to be gained?
