This really depends on the road system, I am somewhat confident that I can get to the countryside on some alternative routes that I know from when I was younger, and it's perpendicular to the direction everyone would be fleeing (I assume). As with any plan, it's good to have it, but they seldom survive contact with reality, so it's important to be able to adapt and improvise. There's also maybe a difference in culture, and family structure; we're pretty close in these here parts when push comes to shove so we can have a powerful network effect going. I can't speak for everyone, but there are a couple of people I know I could reasonably coordinate with to get as many loved ones as possible to safety, and we're already drafting out some lightweight plans.
