Difficult. Yes, of course it can be avoided with goodwill on both sides and modern electronics. Goodwill is, unfortunately, obviously lacking from the European side. So, it has to be a hard border then. It will only hold up people for a few mins. - there can be a 'fasttrack lane for daily or regular users - an electronic recognition system for exampled. The EU doesn't seem to understand that there are some things which are simply not negotiable and that we will just not accept.
We've offered solutions (and money); they haven't budged - they don't seem to know how to negotiate. OK - hard Brexit and hard border it is, then. Let's get ready for it.
(PS They were never going to negotiate - they want to scare other countries. Wish our useless lot would stand up and say 'Right, then....'.
