Hulk I can understand, its his job to understand that his braking will be comprimised if he jumps up the inside and if he causes contact its his fault, it's just a slightly mitigating factor. Vettel, no idea, certain people seem to get away with stuff all the time.
That might excuse the yellow flag, but he flat out caused a collision, with no issues with the track conditions causing it, just turned in on Senna and caused Senna to hit someone else as well, he caused damage to 3 cars including his own, not a clue how that isn't a penalty.
I can't help but feel overall he gets away with a lot as does the team, a wing everyone knows breaks the spirit of the rules, but passes a ridiculously awful test. I love the innovation of their car, I really do, but a clear set of rules so everyone at least follows the same rules rather than ambigious ones that certain teams willfully misinterpret to their advantage I really don't like.
IE if the rules said, the wings can flex, then Red bull would have the same wing they do now, but other teams would all have tried to develop their own.
