The problem this guy makes is thinking The Grand Tour is a factual show when it's clearly more an entertainment show, and I don't think they even attempt to hide that fact. TG was no different, and a lot of the film elements were extremely staged, scripted and situations set up.
It would be ok if the people watching it treated Clarkson, May and Hammond in the way they used to treat Alf Garnet. If the 'humour' is that a bunch of unfunny xenophobes, who are deep into their mid-life crises, can't get to grips with the modern world then fine. Sadly I think that the people who watch that shite tend to identify with Clarkson's world view rather than laugh at it's pathetic absurdity.
TGT Humour 101:
Foreigners are a bit poncy (and probably all gay - which is a bad thing in TGT world).
Healthy eating is for foreigners, poofs and birds.
Electric cars are for foreigners, poofs and birds... (there's a pattern to this).
Spending your working life in a sub-homoerotic fantasy family (Clarkson as bear-daddy, May as the 'wife' and Hammond the weird man-baby) with no women is completely normal. Spending time with women is for foreigners, poofs and other women.
And of course:
Petrol cars are for real men...
