They’re occasionally the crisp of choice in pubs; an excellent accompaniment to an 80/-. Suppose there’s worse criteria for your pub crawls. But aye, a weird omission - you’d be thinking there’s plenty of wagons on the Stranraer ferry that could bring a few palletloads over.
From a UK perspective, a lot of US cars would be illegal to drive on public roads here - too large, too dangerous for pedestrians and other road users. “Dangerous” also applies to some of your other potential exports too. Chlorinated chicken, for instance, isn’t considered safe for consumption. So the absence of a market for those goods isn’t simply “customer preference”.
As a European, we’ve been too dependent on the US on some things for too long. We need to be more independent. The situation in Ukraine has shown that; we need to be able to support our allies better. But the US trashing their own economy, making themselves into global pariahs and handing over their superpower status to China is what I would have described as “not my dream way” of achieving that.
