Typical Ghanaian Traffic Scene--Pop Quiz

There are many scenes in any capital that we see so many times we take for granted. I though in the interests of creativity, I'd offer a pop quiz...with answers to follow later.

1. Why does that white mini-van have a yellow number plate, when most number plates--of private cars anyway--are white?

2. Why is that car behind van in double colours? Did it go through a time warp back to the seventies when outrageous and psychedelic double colours were, like, the in-thing? (so my parents tell me!)

3. Apart from begging, what do you think the guy in the green shirt (to the right of the picture) could be doing?
