In some scenarios, where government learns of a big problem before the populace does, they'll use National Guard to keep routes clear so disaster response does not get stuck in panic traffic.
Say they know nukes are about to be launched. They'll send police, fire, EMT, medical, "leaders" and other stuff out of a target urban zone, then keep routes back in clear. This may happen with a meteor strike IF, if they can get an hours warning.
So when you hear "remain calm and remain in your homes" there may well be armed people keeping you off the good roads, so that the cops and fire and evacuation trucks can move.
And if there is a huge epidemic, the Powers That Be won't allow people to move around and potentially spread the disease. In that case expect to meet force wearing MOPP 4 suits telling you to go home.
So when planning your bug-out, keep in mind that the guys in control already have plans in place, too, and people, vehicles and stored fuel to act out those plans. They'll be willing to risk some people by bottling them up so that a greater number of people, overall, will come out OK.
