I believe that even the Automotive industry will have heard of Brexit and yet they are putting money into the UK... I wonder why? We currently can sell to any country in the world unless they are subject to sanctions and we can buy from any country in the world provided they are not subject to sanctions, the difference is we will shortly be in a position to reduce tariffs on goods that we need from any country we like and they can reduce tariffs on goods they would like to buy from us... We can have a list of tariffs for each country... Hmm, what shall we call it? how about "Trade agreement"? This means that the UK could buy produce from say, some North African country that produces lots of salad produce instead of buying it from an EU country for the same price or less and they can sell into a pretty big market when they have little chance of selling into the EU market... The UK helps poor African countries work their way to prosperity whilst the EU watches them starve, then dumps lots of cheap food on them putting their farmers out of business... The UK yet again is the saviour of the day.
