A lot of team bosses use that phrase. But admittedly, I don't know if it's true or not. From the outside, it's impossible to judge the development role a driver plays.
Don't get me wrong: I like Webber. He's perhaps the nicest of all F1 drivers and I hope he stays in the sport just as long as Schumacher. But it just seems increasingly unlikely that's going to happen. This year, there was hope he'd gotten on top of his problems and even beating Vettel, but then in Bahrain, finger-boy suddenly found half a second in qualifying and a full second in the race again, just because he finally likes the car now. It was the exact same story as last year. Vettel, dominating at the front. Webber, having to fight for his place and still only finishing fourth
