On equal tyres yes, but when your tyres have hit the cliff then it becomes stupidity. The racing incident is of course Maldonado's fault, but I take that as a given because he's such a mentalist and i'm personally uncomfortable with him even being allowed to drive an F1 car - so with this taken into account, Hamilton should have given him a wide berth.
I'm speaking from the perspective of a Hamilton fan, so I want him to do as well as possible and maximise his opportunities - he didn't do that today, Maldonado's fault or not.
