Do you really thing Germany is willing to watch their industry suffer, Germany have already said several times that their priority is the EU so they are prepared to lose trade with us to keep it together.
I am half English and half German and it looks to me a case of the average Brexiteer thinking the Germans are just saying this as a ploy and that they will back down. They aren't, they are direct and operate in a different way to the British. They don't wish us harm are feel sorry for us, don't really understand what is going on (My Aunt the other day-'What is going on on your Island, I don't understand ') They are well aware there are probably more here who want to stay in the EU and are sympathetic so won't deliberately make things hard but they will prioritise the EU and are prepared to lose trade with us, it is not a bluff, you need to believe what you are being told.
Reminds me a bit of when I tried to buy a house. Viewed it and said we wanted to put in an offer. Agent said it might go to sealed bids. Put in offer a little above the guide price which was a good offer and said wanted to secure it would not be prepared to partake in sealed bids. Agent came back to say was going to sealed bids, I said ok, not interested then , thanks. Found a different house that was more expensive that hadn't looked at as was out of price range with 4 beds rather than 3 and detached rather than semi so much better and because we were in a good position got an offer accepted on that.
4 times the Agent called us asking if we were putting in a bid including an hour after the sealed bids were closed. He obviously thought I was bluffing when I said we'd found something else. He did sell it eventually, not quite for what we offered so client was pissed off, his commission was fractionally less and he made a lot more work for himself, all because he was an arrogant tosser who did not believe what I said and thought we were engaged in playing a game which was one sided and only on his side. House we bought had potential to extend and when finished will be worth about twice of house 1 so I'm pleased it happened and shows me being straight and honest pays off for me in the end.
Saw Brexit the Musical the other day, really good. 13 year old DC joined DH and I in laughing our way through it. Any scientists on the thread with suggestions of how to guide very science minded DC in current climate would be very grateful. I feel at a bit of a loss.
