The car industry is struggling - but the German economy is more than VW..
(And they are quite distinguishable. The far right is way worse at it than the kind of left party that wins anything.)
I have no idea what these indicators you're talking about are exactly. The indicators I'm seeing is that Germany was cut off from cheap pipeline gas that its industrial economy was built on, and now there's another energy shock from war on Iran. On top of that, China is now taking over the same industrial niches enjoying access to much cheaper energy which lower input costs across the board.
