People keep completely ignoring the changing track conditions, how did Sutil go off. Drivers don't know the 100% safe speed yet the rules mean you have to be as close to the limit as possible rather than having a rule that means people go no where near the limit of safety.
It was raining heavily with worsening track conditions, these are the very conditions drivers go off in frequently throughout the history of the sport, again this is all absolutely known before anyone sends marshals or vehicles out into the area. Why has any F1 driver ever gone off in the wet? because before you get to the corner you don't know what is a safe speed for it? How many times in the history of F1 has one guy gone off in changing conditions followed by multiple other drivers in the same corner even though they all went slower every lap?
The probability of another car going off on a notorious corner in changing and worsening conditions was significantly higher than normal thus making a decision to send people out without neutralising the race was absolutely reckless.
As you say, his job is to get round as fast as possible, double yellows, single yellow, it encourages you to skirt the safety line. The driver can't see if it's raining on that corner while he's going around, he doesn't know if that corner is getting worse while on the opposite side of the track, he placed his safety in the... safety officers, who are paid to make decisions about when it's safe or not to recover vehicles, without hindsight, with years of similar incidents it was 100% clear it wasn't safe yet. It's 100% clear double yellows do not, have never and will never neutralise the race or make anywhere safe, it's a warning and not much else..
