Given that Alonso was not penalized, I don't think we are in any danger of "nanny" racing. Not that I think he should have been penalized, because that was a great opportunistic move.
The VSC was likely because they used the tractor to remove the car. Not taking chances on Bianchi, pt. 2. I bet Hamilton wishes it hadn't been called. Almost certainly cost him an additional 3 points advantage over Rosberg.
