It isn't even thinking ahead. It is pure, plain and simple arrogance, of the most despicable and stupid kind. The German auto producers are used to be able to strong-arm politicians and their suppliers. What they say goes, because usually they can threaten whole regions with unemployment and whole companies (the ones that produce car-parts such as seat cushions or engine parts mostly/only) with bankruptcy. Don't want to accept a mandatory 20% price reduction mid-contract? We'll just delay payment until you do, good luck surviving long enough for the courts to recognize your claim...

With chip makers, it is different, because chips can be used in lots of different products and there is lots of demand from all corners. So car makers tried their usual strong-arm tactics and failed miserably. Chips being a sellers market, after all. After which car makers went whining to their politician puppets, getting them to OK billions in subsidies for "supply chain security".
