I too am perplexed with this bold declaration by number of "experts" on this BB that unless you can drive a car competitively on latest specification tires, than you are not fit to drive in F1. (Thus telling MS to retire). I am rather thinking that sometimes it is more difficult to unlearn your craft which you honed over a decade or longer, and then re-learn again, than starting from scratch, which essentially many have done. Vettel, would be one of them, whereas Webber, like Schumacher, took their time.
What are you saying?
That it is tougher for someone like Schumacher to adapt to the new regs, ie., tires, than it is for someone like Vettel?
Or that Shumacher and Webber took a decade to hone their race carft whereas Vettel honed his almost from the start of his F1 career?
