The UK are right on Russia's tail and putting people in jail for 3 years+ for writing hurty words on Twitter and Facebook,
even when these words were written only on their own FB profile and the profile was locked down amongst "friends".

Note: the average UK jail sentence for knife crime is less than 8 months.

There have even been suggestions the UK should remove access to Twitter and try to arrest Elon Musk if he set foot in the UK
as people are trying to take his "Civil War is inevitable in the UK" tweet out of context and claim he is calling for that and had a hand in the riots sparked by the murder of 3
little girls by a second generation immigrant criminal.

So the UK government literally want to go after an African-American for free speech, living in the largest country that declared independence from the British Empire.
Let that sink in.

If I were Musk with that type of F Y money, I would play the biggest card that would completely screw the UK government over with its EV plans for 2030:
End all new Tesla car sales end of this year until 2031 and operate a maintenance only service for 6 years.

Did you even look at those? They look like Honda Fit (discontinued).
With 100% tariff it would be $20K, same as Fit, more or less.
That said, do I think that Model S and X are overpriced?
You betcha, but the cost of sales in China has not much to do with cost of sales in US or GB.

Same with almost any good: cigs, potatoes, medications.
Cars would have to travel on a ship across two oceans to get to GB.
