Not quite sure what point you're trying to make; care to elaborate?

Well, you mentioned Ford turning out the Focus, Fiesta, and Transit. Maybe you're so young that these have all been made through your entire lifetime, but I can remember the Sierra (a real innovation, not to mention pig-ugly) coming into being - and where is that now? So yes, Ford are making the Focus, but it's not something they've made since the dawn of time. Cars are a poor analogy, as bits of wood with strings on don't become completely superseded.
