Politics, man, politics.
How so? I don't know. But that's what Paul Ricard head honcho Jean Alesi just said a few days ago. He was complaining that the French don't support it.
Yeah, maybe politics. But I'm far more cynical than that and I think money is the problem. It's always the money.
"“Having a French GP looks good on the F1 calendar, but if we don’t have the possibility to do it, then that’s because the country is not interested in motorsport, and that is a big shame,” Alesi added. “It’s not a problem for F1 to have a Grand Prix in France, the blame is on France."
