Wait, what? So they're retaining a driver to avoid riots at a future race?5. These rumours have now been refined - while Liberty "might" have been involved, the driving force is claimed to be Perez's main sponsor Carlos Slim. Perez is retained to ensure "sponsor and team stability". Rumours suggest Slim convinced Red Bull that there would be security risks at the Mexican GP if Perez was dropped. Liberty, on the other hand, are claimed to be worried about ticket sales and merchandise revenue.
That seems like a sub-optimal way to run a sport.
