It's part of the fact that F1 cars are easier to drive than ever before: traction control, etc.
Not to take anything away from Hamilton though. The guy has been a sensation, and there's absolutely no reason to talk down his achievements. Kimi Raikkonen has been driving like a slug. It's amazing how much talent this guy supposedly has, but it looks like he just doesn't give a damn. Rumor has it that he's a heavy drinker and a party boy, and doesn't really care about developing the car. Not to mention he has a personality and articulation of a beached whale.
