That's funny, Heng - there you are talking about shoulds and
should-nots, and in the very next breath you're going on about how
Alonso shouldn't b!tch. Now do we go with "shoulds" or don't we?

And if you want to talk about drivers exercising judgement, well,
yeah, you're right. I suppose at the end of 2003 Kimi would have
been ruing the day that he piled into the back of Pizzonia, costing
him the points that would have made him 2003 WDC. Iceman -
riiiiight. 
2003's a great year for assessing Kimi's performance. Michelin had
the edge over Bridgestone, and the WDC was almost within his grasp
- almost.
Kimi could have made up the points he needed by pushing JPM (with a
busted engine) at Monaco, but he played the percentages and hung
back way too far to take advantage. Whoops - wrong
percentages.
And what happened after the third pitstop in France? Kimi literally
gave MS third place.
Oh, and the British GP, that's a real beauty. Some clown in a kilt
literally hands Kimi the lead and what does he do? He gives not
only first to Rubens, but second to JPM. Real cool.
Sure, there's no denying that Kimi's quick, very possibly quicker
than Alonso. Hell, by Brazil 2003 I was hoping that he'd be WDC,
and it was his to take while Ferrari were trying to find their feet
mid-season, but in Monaco, France and Britain he played the
percenatges. Think about it - what if he'd gunned it? Kimi's fast,
but he's going to need the aggressiveness to go, "Oh no you don't"
when another driver's having a good day. For a positive
demonstration, watch Alonso holding off MS in the closing laps of
Imola 2005. Kimi, on the other hand, is either romping off in the
lead with a clearly superior car, or he's playing it so safe that
more aggressive drivers rape him for points.
And sure, he doesn't b!tch about things like that - why should he
gripe about being faster when other drivers are passing him for
position? He just shrugs his shoulders, says "Oh well", then goes
out and takes out his misplaced aggression by getting blasted at
the end of the season, making a complete ass of himself. 
If you want to call Alonso a hothead, I don't think there's anybody
who would disagree with you on that one. Then again, Senna was
regarded as one of the biggest hotheads around, especially when he
won his first WDC in 1988. When it comes to wheel-to-wheel racing,
it's going to make all the difference, it's going to make the
crucial points to decide a WDC, and it's what makes the difference
between a racer and a driver.
