The self sufficient communities have a better chance of forming if the big changes before the pole shift come in incremental steps, so that more of the (aware) people at some point will decide to "make the move". If you really know for sure that staying in the city is going to be a death trap, then you're going to carry out plans to move out. For now, there's still too much inertia to make the effort for a lot of people, not having had any experience of related life threatening "events".

It's also a good idea to make sure you have some mobility without counting on the use of the car. A possible CME scenario (August/Sept this year?) could disable the whole transport system. A bicycle would still allow you to move and get to your country place.
