I agree... Harsh on Perez and mind blowing with Gutierrez, that fight with Maldonado, Sutil and DiResta was the best of the season so far.
Vergne and Hulkenberg pushed each other off the track and nothing was seen by the stewards, Sutil touched Maldonado before the Venezuelan tried to enter the pits for a new wing (extremely optimistic manoeuvre by him), and also the drs of Grosjean was active when Perez attacked him... and no car was ahead of him.
If you think it's harsh on Perez it might help if you explained why. Grosjean got the DRS from Kimi who was right in front of him - look at the video and try it with your eyes open this time!
Regarding JEV and Hulk, just because a car leaves the circuit does not mean it was forced off or that it should be deemed to have gained an advantage. Nobody was penalised simply for going off, there was lots of corner-cutting especially at Radillon, and Webber ran off the track at the exit of Pouhon every single lap as far as I could see, but I don't hear you complaining about that. Gutierrez was penalised for blatantly driving off the circuit to make a pass - that's a different thing. It's regarded as gaining an advantage while the other examples of off-track driving are (rightly or wrongly) regarded as mistakes with no advantage gained.
Not sure what point you're trying to make regarding Sutil but if you're agreeing with Maldonado's assessment, that Sutil should have given Maldonado more room, I don't know how much room you want him to leave on the inside? A car's width is normally considered adequate. The collision occurred because Maldonado didn't turn in - it was a left-hand bend and Maldonado was going straight on. Maybe he was trying to pit in which case he's lucky he's not banned for Monza, or maybe he was just trying to take a very wide line in so he could straighten the a car early for the apex, in which case he is guilty of a major misjudgement of the situation..
