jctk: I agree on that, but it's not something they can magically change for this particular decision. But yes, the regulations are probably wrong there, it should be 15 or 20 seconds, as that's about how much track time a drive through costs on most circuits.
As for the points about previous decisions, well, I think it's a dangerous road to go down, as it just opens twenty million cans of worms. FWIW I though the Kimi and Massa decisions were sensible. The thing with the Massa incident is it's hard to issue a sanction on the basis that it's Massa's fault - that's hard to prove. So it's a bit tough to issue a sanction that costs Massa in terms of championship chances for an incident that may not even have been his fault. I think it's good for the sport to let that one ride without penalizing Massa, though they could have issued a more meaningful sanction to the *team* somehow.
Again with Raikkonen in Monaco I can see the decision there. It was simply a flat out mistake / accident - either Raikkonen overbraked or he got unlucky and hit something on the track. There was absolutely no reason for him to intentionally take out Sutil, and I don't think anyone has even suggested that was the case. Again I think it would be bad for the sport for him to be artificially hurt in the standings for what was either an honest mistake or an unlucky accident.
For me the thing is, if you establish a perfectly sensible precedent with decisions like that - of not enforcing regulations to the strictest extent in the interests of letting the championship play out fairly - why throw it out of the window when it comes to Hamilton? Aside from the whole debate about whether Hamilton did anything wrong, even if you were to accept for the purposes of argument that he did, the prior incidents clearly set a precedent for not giving Hamilton a points penalty, since the incident in the end did not materially affect the outcome of the race. It's very hard, IMHO, to support *both* the penalties given to Raikkonen and Massa *and* the penalty given to Hamilton. I think the former were correct, I don't think Raikkonen or Massa should have been punished any more than they were...but in that context, even if it were undeniable that Hamilton had been at fault in the incident with Raikkonen, the punishment meted out seems unduly harsh.
