So, in a way the zombie apocolypse is here isn't it?

Walk down just about any town-centre in the evening, or march-up to use a cash point,  and swaying, stumbling zombies approach you - mumbling about needing £2 for a coffee, after trying to sell you the big issue.

You can see how this subconscious realisation is starting to be employed by the advertisers -

"It's a nasty world out there, secure yourself in this massive 4 x 4 - or hyprid jeepy weird thing, then you'll be safe".
