Transport remains the main obstacle. There are no trains or buses, and as you can see for the video footage, there are not so many cars left either, even if there were roads to drive them on.

Also, many people are reluctant to leave their hometowns, even though there is nothing left, and others won't leave until their lost family members are accounted for.

Many will eventually move to other places, but most will likely not go far. Plans are already being considered, and something will be figured out.
