I understood that the UK border checks in Dover etc, are mostly done on-line and automatically and that only about 1 in 10 are physically checked and that this method would continue when (if ever) we’re outside the EU. Most border checks are only done to catch illegal immigrants and drug smugglers. Technology is now at such a state that physical hard borders really aren’t as imperative. Yes, locals will cross the border to top up petrol on whichever side is cheapest, but that will happen anyway, having to scan a passport through a machine in the same way as going through a toll bridge isn’t going to make that much difference. I don’t think a hard border will mean a Berlin Wall or two lines of razor wire with a mine field between. At the moment there’s a lot of scare mongering, posturing and threats. Eire needs to export to the UK through Northern Ireland. Northern Ireland doesn’t actually do much trade to the south.
