I know that way back in the 50s and 60s companies like Ford actually had huge factories in the UK building cars for the European market. But it seems to me that they have all retreated to their own insular North American island.

I do appreciate the fact that letting China control domestic car markets completely is not in geopolitical interests of governments, especially since US and EU can’t beat the Chinese in a free market. Plus it’s likely these highly advanced vehicles have atleast some intentional vulnerabilities and backdoors.
