oh lord, if it was such a huge advantage why doesn’t McLaren, Ferrari or whoever spend 5 bucks to buy HRT so they can also have “easy overtakes”. The total timeloss for a RB/Ferrari/McLaren overtaking an STR is about 5 seconds. Who cares. Back in 2007 Coulthard said if Hamilton came to overtake him in the race he wouldn’t interfere because he didn’t want the negative media coverage of blocking a British F1 Championship candidate. And promptly Coulthard moved all the way to the edge of the track in front of the pits when Hamilton overtook him. Nobody was outraged.
Marshal Sector 4 (basically the straight after turn 3) was green flagged by the flag marshal in Post 5 on Lap 3. Vettel overtook a Marussia on Lap 3 and the Toro Rosso on Lap 4. You guys are making mountains out of molehills just cause some random dude called George Whatever tells you on youtube if you see yellow light on the cockpit then it’s a yellow zone … cockpit lights synch to sensors on light stations, not every marshal’s post has a light station attached (and post 5 in Interlagos doesn’t have any lights) and drivers have to obey flags first and foremost, lights are supplementary signals.
