The FIA's inability to bring the guilty to the rule book and let the serial offender escape, should spur the Mercedes to enhance their car performance in anger and dominate again. That would be the best answer to the stewards' inefficiency and of the FIA's, who are worried to punish Vettel, ONLY because it would affect the championship fight, in spite of full knowledge that it was a deliberate crime.
I would wish for the uni-dominance of Mercedes to be back as Vettel, doesn't deserve to fight for championship anymore.
