_Higher_ education is actually an export industry in the sense that foreigners spend lots of money on it, but the government hates it for various reasons and it's currently on strike as a result.
That’s what I can think of off the top of my head and there a plenty of automotive suppliers and start ups in the area
UK automotive is a massive industry and still very relevant in the midlands.
Not really, Mexico made three times as many cars as the UK in 2021.
You named many companies, I'll ignore their foreign ownership, but Lotus, London Taxi ,Jaguar, and Aston are low volume
Aston isn’t owned by an international firm, they have heavy Daimler investment but for all intents and purposes they are independent (although I can’t see it staying that way for long they desperately need the weight of a larger firm backing them - like Lotus has)
I completely agree the UK focuses more on low-volume, high-value automotive, bit looking at that table UK car production has more than halved since the Brexit referendum went through. The hollowing out of the UK car industry is a very recent phenomena.
And education is awesome, which of course is why we strictly limit building around our top university towns and cities.
