But the stickiness of geography for finance and autos are very different. Replicating a segment of London's financial sector in Frankfurt is easier than replicating BMW/VW to UK.
Cars are ultimate commodity - you can buy Lexus or BMW and they are mostly equivalent. I am sure Toyota or Honda will be happy to sell cars in UK. Import to UK from EU is almost 1.5x higher than reverse. Tariffs will cost EU more than UK.
