Imari is correct, for a start there is a "United colours of Beneton" setup going on, from Europe they have one guy from the following countries - UK, Spain, France, Belgium, Russia and Germany, chances are the guy this time will be from one of the countries who have not already won, yes you need to do well behind the wheel to get to the last 6 but after that the judges pick the winner rather than racing for it, and they are hired by Nissan.
The point is you have to remeber that the winner has to be one of the faces of Nissan , i.e. polite, likeable, personable etc. etc. , you think if the very best driver there was rude and brash that Nissan would be happy to ascociate his/her face with thier brand and have him doing interviews on camera platered in Nissan logos?
Yes there is a huge opportunity for one of the drivers, but if you honestly believe they are pumping all this money into finding a good driver for racings sake then you are very niave, its a marketing exercise at the end of the day.
