Totally agree. The whole process has been a farce. I'm not even particularly fond of the EU, but the way the UK has conducted itself is a diagrace and will not stand us in good stead when negotiating future deals with other nations. It seems "head in the sand" is the default position for those supporting Brexit at any cost.
The accepted definition of what brexit is has changed so many times, it shows that it is all based on rhetoric. In 2016 we were told it would be impossible that we wouldn't get a deal. Mercedes, BMW etc want to sell us their cars. No deal was out of the question. Now we are teetering on the edge of a no deal brexit and that is being sold to us as a great thing for the nation. Ridiculous.
Brexit was started from lies and to cover the lies they had to invent more lies and it has snowballed to such a point that they can't even remember which lies they've told.
Even the German car myth was so ridiculous if people just thought about it for 5 minutes or bothered to inform themselves. They will still sell their cars with or without a deal, they might become more expensive for British people , there may be delays, spare parts will take longer to reach dealers etc but a luxury car purchaser won't be so troubled about paying 80k instead of 70k for example.
Of course German car manufacturers would prefer that they could sell their cars without import/export controls but it's only one market.
Whereas the industry in biggest danger is actually the British car manufacturers, who are just about all foreign owned - why keep the factories in the UK if it causes so many problems and delays exporting them. The only reason to keep any there would be for the British market but even then the parts have to cross borders several times to assemble them. Cars are currently the top UK export worldwide - why endanger that?
Even the argument about the UK having individually styled trade deals to suit them better actually shows itself to be a joke with the Japan deal. What it apparently means is they want to sell a few British products worth a few million as well as the normal trade deal the EU negotiated.
But that doesn't mean that the UK have actually sold cornish pasties or stilton cheese to Japan, they have got a concession from Japan to reduce the tariffs on those products but the customers in Japan have still got to want to buy them. In exchange what has been the concession been to Japan, that they can sell more cars to the UK?
But Brexiters knew exactly what they voted for - only they aren't able to say what it is.
