Given that the car industry here in Germany opposed the (even much more moderate) tariffs the state subsidies certainly don't seem to scare them more than a trade war. It's just a repeat of the automotive industry dark ages of the 70s/80s when tariffs vis-à-vis Japan were enacted based on the same reasoning. You're just gonna have 20 years of no competition.

China is going to win the markets in the rest of the world, which is where the bulk of cars go now. It's gonna be funny when everyone in Asia is driving a 15k modern electric car and we sit here driving old second hand gas cars behind a tariff wall. It's like a reverse Soviet Union situation

Even say EU vs US is not so rosy in trade wars. Remember how German government played down VW's dieselgate? Every single state has something similar, even if not on same scale.
