I'd be surprised if it went more than a few races.
IMHO, I think JPM's temperament is what did him in over in F1. He just wasn't cool headed enough to become a champion. Talented no doubt, but to become a consistent winner you need lots more than just talent and good equipment.
And now there are rumors of Jacques perhaps making the move too. Another one with a slight hothead.
At the very least, with those 3 in the same race there will be lots of work for the body shop come Monday morning!!
