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

[Lightspeed]

If Joe Soap and his family had the wherewithal to get out of the city before the general stampeed, this would show that Joe or someone in his party have some situational awareness.

Getting gridlocked at say Swindon would therefore reinforce the correctness of their decision to evacuate. It would also motivate them very strongly to keep moving away from danger.

Maybe the gridlock would force the Soaps to draw breath and re-appraise their plan, and take note of the numbers of other people with the same idea as them. Either they would adapt their plan or with no other options press on.

Its all about motivation and expectation. If they are motivated to keep putting distance between themselves and the City, and have an expectation of being able to make a go of it at their destination, they will press on.

BTW re blockading Devon. Am I right in remembering that Devon has the longest road network of any county in the UK... something like 7,500 miles worth I think? That's a lot of roads to block.
