Trade wars work both ways. So far the US export market is not doing so great. All those tariffs are raising the cost of exported goods as well. And those were already too expensive before the tariffs. If the US wants more US cars on EU roads, it needs to start making better cars. It's that simple. But in the EU, cars have to compete with domestic cheap cars and imported Korean and Chinese cars. It's a level playing field. Hence not a lot of US cars on the roads. A few Teslas (made in the EU mostly), a few Fords (some made on the VW platform), and a sprinkling of niche imports for things like muscle cars and pickup trucks. They are quite rare but you see one or two once in a while.
