Lewis Hamilton said his confidence remained unshaken despite a pit-lane blunder that knocked himself and Ferrari rival Kimi Raikkonen out of last weekend's Canadian Grand Prix.

The 23-year-old McLaren driver lost the Formula One championship lead and was handed a 10-place penalty on the starting grid for next week's French Grand Prix after the collision.

"This will make no difference," said Hamilton.

"It hasn't knocked me confidence-wise. I'm not gutted or disappointed.

"It is not going to take me a day to recover or anything. I will be up first thing training and really looking forward to Magny-Cours."

The Brit ploughed into the back of world champion Raikkonen's stationary Ferrari at the Circuit Gilles Villeneuve on Sunday after the Finn had stopped for a red light at the pit lane exit.

The light was on because the safety car was deployed while marshals removed Adrian Sutil's stranded Force India from the side of the track.

Raikkonen said afterwards that the collision was inexplicable and stupid.

"The rule is silly," Hamilton told the Daily Express.

"We are in the race, how can you red light at the end of the pit-lane? But that's the rule and I accept it.

"I start 10 places back in the next race. It's a bit harsh, I didn't aim to ruin anyone's race," he added.

"Going forward, the mood is strong. The fact is we destroyed everyone at the weekend. With the car we have right now there is no stopping us."
