Not so, the Japanese and Koreans can build and transport cars to the UK cheaper than France or Germany, without the crippling EUSSR protectionist tariffs. Now ask about TVs Washing Machines, etc. etc. Did you know that the EUSSR zoned areas of productivity for consumer goods many years ago? White goods, righto Turin that's yours. Steel, ahh we keep that in Germany with a bit for France, and so on, and so on.
