Hamilton becoming a menace

Lewis Hamilton needs to think as quickly as he drives. With some smarter decision-making, he could have avoided many of the multiple incidents he has caused this year.

In Singapore on Sunday he again misjudged a passing maneuver and found himself penalized with a "drive through" the pits. The collision also caused a puncture - and wrecked race - for Felipe Massa. The Ferrari driver confronted Hamilton in the media "bull ring" after the race. "Nice job," he said, sarcastically, giving the Briton a thumbs-up.

Hamilton is the fastest, most instinctive and exciting driver in F1 today - but he is also the most impulsive. And that can lead to trouble in a sport that, especially these days, requires a lot of thought.
