You're forgeting the ones who may get there before gridlock....could be quite a few.....roads are very obvious and a lateral thinker may be able to circumnavigate the chokepoints...just for example...why not use the railways if you have a suitably sturdy car(4x4, van or truck)obviously trains will have stopped running long since , many access points are available to road vehicles just need a pair of boltcrops.
