If it was just the one incident yesterday I would agree, however with all of the events this year (quali at Monaco for example) it does seem Rosberg is deploying underhanded tactics to win the championship over his team mate.
All of the racing drivers spit their dummy out, and Rosberg is certainly one of the worst if anything, 'waaa, why won't he let me past, waaa waaa'
Even toto didn't agree that it was 'just a racing incident' & I would very much imagine he knows more about the sport than us.
Roseberg wasn't committing himself to going out of the race either, he is only racing Hamilton. If Hamilton is out, any points scoring position is a win for him.
I don't think the fans are spitting their dummy out either, I guess people are just upset & disappointed for him, which is only a natural reaction to loosing in this way. That's what makes you a fan I guess. Win & loose together.
The thing is, whenever those two race fairly without incident, Hamilton always comes out on top thus the need for underhanded techniques. IMHO anyway.
