The Croydon Challenge.... Does It Have Punk Rock, And Is It Craaaaaaaaaaazy?

I was looking for a writing challenge, but I found an advertisement for a taxi service in London! Interesting place to advertise, and I have to admit that I will remember the Croydon name should I ever find myself in London....

So how does one win this challenge? Is this a writing challenge at all? Is this a pay to win challenge, like booking a taxi will bring about victory? Would riding in one of these taxis be like playing the classic arcade game Crazy Taxi? Because if I am going to consider these services in my next (first) trip to London, I am hoping for some Offspring and Bad Religion blasting out of the the Croydon taxi speakers..... that would be radically radical!

Now I need to go play some Crazy Taxi while I wait to see who wins this challenge..... personally I think batmaninwuhan deserves it :-)
