I have a round-about answer to this, but first a question. Short answer is that it is an "innocent fraud" to get money from people.
Where can I find the performance characteristics / specifications of Ford airbag inflators such as any of the below as examples?
To the Poster's discussion:
Car companies are perpetrating what John Kenneth Galbraith would call "innocent fraud" if not actual fraud. They have a policy of constant "parts churn."
Why does Ford need 24 different car horns in the last 10 years (No SUVs nor pickup trucks included)?
Why does Ford need 32 different wiper motors in the last 10 year?
And considering all the hell brought on by airbag inflators, I would really like to know if Ford needed 80 different airbag inflators in ten years or if it was just "revenue enhancement."
Maybe Henry Ford was the only one of the lot with any morality.
It is considered good manufacturing practice, and not bad ethics, occasionally to change designs so that old models will become obsolete and new ones will have to be bought either because repair parts for the old cannot be had, or because the new model offers a new sales argument which can be used to persuade a consumer to scrap what he has and buy something new. . . .
Our principle of business is precisely to the contrary. . . . The parts of a specific model are not only interchangeable with all other cars of that model, but they are interchangeable with similar parts on all the cars that we have turned out. . . .
