Rivals defend Hamilton's driving

Former world champion Jacques Villeneuve questioned Hamilton's defensive moves off the start of races, claiming that other drivers would have been punished if they had acted as the rookie did.

But Villeneuve's views have not found support in the paddock at Montreal, with Hamilton's rivals all in agreement that he has done nothing wrong.

BMW Sauber's Nick Heidfeld, who has started most of this season's races right behind Hamilton, has said that he was not aware of anything that could be cause for concern.

"I've not seen anything from in the car or also when I have watched the races on television afterwards - although I haven't focused specifically on him," he said when asked by autosport.com about Villeneuve's comments.

"I definitely didn't see anything...have you seen anything?"

Red Bull Racing's Mark Webber acknowledged that Hamilton had been aggressive at starts, but felt he had not overstepped the mark on what was acceptable.

"I saw a replay of Malaysia and he was a little bit cheeky with Massa, but it was alright," said the Australian. "We've all got good memories."

Williams' Alexander Wurz claimed that the controversy probably had more to do with Villeneuve trying to stay in the spotlight.

"I think Jacques might find it more and more difficult in the future to find comments that we can be asked about," he said. "I see nothing wrong with the moves he [Hamilton] is making. It's hard to defend your line."

Giancarlo Fisichella added: "Jacques says quite a lot of things in the media right now. He talks too much."
