Once the catastrophe presents itself, the natural inclination will be to bug out to a safer location. The problem is that will be everybody else's inclination as well, so it's important to keep your ear to the proverbial grindstone and not be caught having to quickly load whatever groceries are possible into the car and take off amidst all of the other refugees. Interestingly, the family in the show actually did a pretty good job of trying to be ahead of the curve in this respect, but it wouldn't be a television drama if such well-laid plans had actually worked out for them.
Also, it's worth considering that bugging out itself could present a certain level of danger. Not only are there the hazards of the road in a potential emergency situation to deal with, there's also the potential – in the case of a disease pandemic – that people bugging out and migrating to look for safety might actually spread the contagion further. This is a point where one would have to decide between bugging out or sheltering in place, carefully weighing the strengths and consequences of both potential plans for survival. It's also important that if you do decide bugging out is the safest option for you and your family, but the situation necessitates you becoming separated, that you set a rendezvous point to ensure that you and yours are able to get back together later rather than one party unnecessarily having to wait for another to return from some errand.
When things begin to truly go downhill, don't count on being able to depend on emergency services personnel. Regardless of their personal work ethic and calling to perform public-service, normal human instinct will dictate that they concern themselves mostly with taking care of their own family first. This probably won't happen until things get truly bad, but it's almost a certainty that it definitely will eventually occur. Studies have been conducted that have proven many simply won't report to work past a certain point a truly serious emergency.
And, one must prepare themselves for the possibility that even people known to them as friends could represent a threat in an emergency situation. This is especially true in the context of a disease pandemic as pictured in the show. Never mind the threat of zombies; all communicable diseases spread through contact person-to-person, so contact with anyone exponentially increases your chances of becoming infected. Couple that with the fact that some people could turn to violence in the wake of a disaster scenario, and one is left needing to prioritize in favor of taking care of family and those close friends for whom you have accepted responsibility to the exclusion of other people, whether you happen to know them or not.
