unfortuunately, KR's mistake was a quite noob, he probably thought that being the last 11 laps of the race and the track drying out he could attack a slower car in front of him but put a wheel wrong. I think he said he tried to give Sutil some breathing space by braking earlier, but that seemed to be a costly mistake.
re: personality
Personality is part of F1 regardless and you ahve to take that along with the driving skills. Obviously different people have different likes and dislikes and will try to justify why they like and hate certain drivers. Just because someone is fast, doesn't mean I have to like him. I think a lot of people like KR is because he doesn't talk himself up, or doesn't talk much at all. Every time when they ask him what are his chances of winning WDC, he always says "it's a long season, still X races to go, anything can happen", to me it comes across as pretty humble. When it comes to Lewis, I think the media is playing him up too much and to some people, ,they don't subscribe to that regardleess how much you cram down their mouth. I mean, look at the publicity thing he did for Vodafone (dangling from a wooden horse was it?), he later said he hated it because it didn't make him look cool and he said "I do have a cool image to maintain" or somewhere along that line. That just seemed pretty arrogant. Then there's the "I want to emulate Senna" comment. I guess you could interpret that in two ways, either 1. I want to be a great racing driver like Senna or 2. I want you all to worship me like you did Senna. Either way, he should not have said it, he should've just kept his mouth shut kept it to himself and once he got there, then he can say "yes I've always wanted to be like Senna". I think Senna was and still is special to most people and they don't want another Senna, just like we don't want another Schumacher. To say he wants to em,ulate and be like him is like saying I want to replace him. To some people, it rubs the wrong way.
I don't hate him, I just don't like him. But I will give credit where it's due, he is one hell of a good driver, ,he just needs to ignore the press and concecntrate on winning.
