No this doesn&#x27;t happen to a large degree.<p>The examples you cite are where existing tooling is used to manufacture a complete product. The Mazda&#x2F;Ford owned assembly line can be set up for either product.<p>There are crazy hard barriers standing in front of fabless car companies, with little benefit.<p>Who wants to buy a car from a manufacturer with no support?  Will the suppliers guarantee parts for 20 years? Or do you want to contribute to landfill problems and tell me to just get a new one?
