So we've had some threads on stewards consistency, but stewards bias was rarely discussed in recent years (Hamilton in Monaco couple of years ago and Verstappen moves this year), but it was always about stewards reactions to what was happening on track.
However, what I found weird today is a situation when Brundle was doing his gridwalk and met with his old friend and FIA Steward, Derek Warwick. They've talked about couple of things and at the end Warwick said "I hope Lewis will win and regain the lead in WDC standings". Obviously, everyone is entitled to have their favorite drivers, but when you become FIA Steward, I would think you should be completely impartial.
I thought it was odd, but what was even more interesting to me was fact that Rosberg got his penalty for overtaking Raikkonen pretty much immediately after Hamilton's engine gave up.
I don't want to discuss whether the penalty was reasonable or not, but the fact that FIA Steward was cheering for a specific driver. I don't think this should be happening (as it indicates that some of the decisions made by FIA are biased) and I am quite disappointed with Warwick's comments.
