Devon and Cornwall will be inundated with refugees? Ifs, maybes, and conjecture

[Midnitemo]

there will be takers for all those options in that scenario , so you'll have quitters who will sit tight too long in the jam and become victims of thieves and looters(i think that this is your worst choice)then some will de camp to the surrounding countryside, some will head of in the general direction of the south west , some will have a change of heart and turn around and head for home , and some will think following the bulk a bad idea and scatter off in all directions...a lot of people snarled up in this jam will have been heading for wales aswell.
