I was pretty much convinced they'd flag Kimi in with that exhaust. Being a Ferrari fan, I'm rather glad they didn't
I'm starting to get a little more agitated on behalf of Hamilton now, having looked at the chicane-hopping again. I can see why the stewards decided to penalise him....but it was pretty bloody harsh. The guy was almost out of control, so it's not as if he gained all that much. If anything, he probably shortened the life expectancy of his tyres somwehat since he was on the softer option ones.
Still, it wouldn't have cost him and the team much for them to get on the radio and say "let him back by Lewis, 'cause you can bet they'll penalise you for that".
