Stewart: Hamilton beginning to crack

Racing legend Sir Jackie Stewart believes the cracks are once again beginning to show in Lewis Hamilton's demeanor, just as the Formula One season enters its decisive period.

"The Japanese race demonstrated that Lewis is still very young, in only his second season, and although he comes across as very cool in interviews, he doesn't always have the same level of mind management when he's racing," Stewart said.

Stewart was speaking in his role as an RBS Ambassador and said he felt that Hamilton's arrogance got the better of him in Japan, as he blew a pole position to ultimately finish in 12th.

"Hamilton's approach in that first corner was slightly arrogant to other drivers. He braked far too late, ran deep into the run-off area, almost collided with Kimi Raikkonen, and was later punished by the stewards with a drive-through penalty.

"That was the 'make it happen' moment of the race. Lewis didn't make it happen for himself; he made it happen for everybody else by taking himself out of contention.

"Lewis Hamilton can still win the championship, but not if he drives the last two races the way he drove in Japan."
