Great race. Massa didn't have enough speed advantage when the other car also had DRS, so not much else he could do. Perez did an amazing job until his last braking zone - silly to move that late. Could clearly see on the live footage what he did, so no idea why people think it was Massa's fault. Rosberg the driver of the race - nursed a very sick car home quite quickly. Might use more fuel than Hamilton, but perhaps is easier on brakes (not normally an issue until they lose the energy recovery and have to survive on the under specced rear brakes.
Good job by Button to somehow leap to 4th. Ricciardo did what he could, but he won't be mega overjoyed as he didn't win totally on merit. Vettel has found some pace recently, so maybe finally getting used to the new style of driving required.
Chilton is okay as long as he's allowed to tootle around at his own pace. Ask any more of him and he becomes a liability (not just in this race).
Not sure what happened to both Lotus. Saw end result, but didn't see cause. Their car still looks evil to drive though, but nobody seems to take that into account.
