I agree with M4gtr on the whole 'FIA are in it for ratings not racing' pov, and yes, it is full of s*#@. However, firstly, it is inherent given the Bernie/Banks/Mosley set-up... Do you really expect the heirarcy aren't going to íntervene when necissary' in order to maintain profits and popular appeal? I'm sure you know that in particular is a major factor? As far as I'm concern, F1 should never of been owned, nor should it ever, fact is however, it is... After Alonso's 'blocking penalty' at Monza last year, I will say I do see your point about total lack of partial judgement within the governing of race weekends, on this year's spying scandal, the jury is still out..
On the 5 car lengths thing, if it is a rule, and Hamilton did not adher to it, then it is legit, as it, be it directly or indireclt (depend on pov), it caused an accident. Remember all those stop-goes and drive throught between 2002 and 2004? Between Ralfie, Montoya, Schumi and co. When they all went argy bargie for a few weekends there and the pit exit line shenanigans??? These rule violations happen, deal with it, it is entirely a driver's resonsibility to pilot the car in acorrect manner that is entirely adherent to the rules and regs.. Simple as that..
