It lowers the complexity sufficiently that traditional car makers in Germany are huffing and puffing about tens of thousands of jobs that won't be needed anymore.
Maybe they want subsidies. The German econony is slowing and this is another reason: people delay the purchase of an ICE vehicle indefinitely (they're going to be banned by 2030s in almost every country), diesel sales are at all time lows (emissions compliance) and the auto industry is stuck with the inventory.
That is funny. I remember reading about just in time production in german magazines since decades. Maybe they shouldn't have produced so much in advance?
