I thought Button was racing Perez harder than he would have raced a normal driver. I thought he was the worse of the 2, I didnt personally see it as Perez swerving at him on a straight. I dunno if it was over the line though. Only thing I cringe every time I see is the way they(Webber puts them there usually I have noticed, but I guess its subjective if thats his fault or whether they shouldnt go there in the first place depending on when they get the overlap) defend on the straight in DRS zone, especially when they go into the pit exit line. Afterall, its there in the first place to stop cars coming out the pits and going towards other cars with a big speed advantage so it kinda defeats the purpose when other cars do it the other way around. It wouldnt affect the racing at all to stop them doing that, and 1 day there is going to be a massive crash, its more likely now than ever with the DRS zones and Pirelli tyres.
