There is a fine line between stuffing it up the inside and maintaining control, and a cynical banzai lunge and relying on the car in front as a cornering aide. It gets difficult to distinguish however, when the car in front turns in mid corner to block the move, or turn so early as to run the passing driver off the road. It really is both drivers responsibilities to keep it clean, and while I'm no football (soccer) fan, an analogy can be made to professional fouls and diving on the edge of the box, both of which are poor sportsmanship.
Maldonado defended poorly before the corner, and must have known firstly that Hamilton was there and all over him, and secondly, that turning in would have resulted in himself being pushed wide. I simply don't think he considered this and it was a rookie mistake that neither driver deserved punishment for, and if anything, Pastor should have had a warning.
The really difficult decision for me, is the Hamilton Massa incident. Massa looked like he was going to try to pass Webber, but his angle and speed would have probably resulted in contact with Webber anyhow. Whether or not he saw Hamilton will remain unknown, but he did move across early, and could have quite easily have been trying to run Hamilton into the barrier. Hamilton on the other hand could have possibly backed off, I'm not sure he had anywhere to go if the pass had pulled off, and it was for this reason he got the penalty. Massa was not the innocent party by any means, and if was able to carry on, it would have been interesting to see if he too was penalised for what was a dirty move either way.
I can fully understand Hamilton feeling hard done by, but his outbursts haven't done him any favours. I'm no fan, but unfortunately there are some people that simply hate him no matter what, and I suspect some of those are within the FIA. His Ali G comment I believe was a poor taste joke I suspect, but there may be an element of truth behind it. The situation is made worse by the inconsistent application of penalties. Kamui - another exciting driver - hit Sutil while passing, and while a racing incident too, was not penalised even though it was a very similar incident. Given these types of scenarios, its no wonder Lewis feels singled out.
Good racing will always be controversial with regard to incidents on the track, but I feel that sometimes off track politics are influencing the "fair" application of rulings, and where huge amounts of money are involved, need to be independently arbitrated. Any other business would have to answer for its actions if questioned after all.
