Re: Missing the obvious
There's a more fundamental case of missing the obvious. Why do the British government want to see experimentation on the British public?
Most of the UK motor industry is upping sticks, and was planning to do so before Brexit, due to high energy costs, high levels of bureaucracy, and high on-costs for labour. Any UK developed intellectual property will be privately owned and so sold, re-sold and rapidly be offshored to a low tax destination, or bought by a US tech corporation (or both). Even of the current UK car makers, they're all foreign owned, so the returns to the UK will be very slim pickings.
Sadly this is just more arts-graduates-politicians-picking-technical-winners. They've heard of AI, blockchain, autonomous vehicles, they must promote these things.
