I aexpected that to happen. I was surprised Michelin didn´t opt out earlier, since they knew this was bound to happen. I think the idea of a single tyresupplier is completely in the opposite direction of what F1 should be. What FIA should´ve done is opened the door to more suppliers instead. The tyremanufacturers should only be allowed to supply two or maybe three teams. That should put a new level to F1. Why can´t FIA try something new? They have already tried using one supplier, and that didn´t exactly work great. If there is no competition, the supplier won´t have to develop the tyre any more, and so the quality of the tyres will slowly degrade, as the cars develop further. Bad idea, FIA!
