Webber: rain harder to deal with in Canada

The Australian thinks the low downforce nature of the Circuit Gilles Villeneuve will make life difficult when it comes to racing with no electronic driver aids if threatened rain showers do come.

"The grip level is low here. We're not on Monaco downforce," said Webber. "In Monaco it helps that we're on maximum downforce, because that switches the tyres on and makes you feel more confident, so everything pulls in the right direction.

"Here, you go out and feel as though you have no talent whatsoever, because you have so little grip. The track is slippery to start with, you've got a lot less downforce on the car and that's the key here.

"The downforce level plays with everyone wet or dry and the cars are more difficult to drive. If we have greasy, changeable conditions on Sunday, they'd better sure they've fuelled the safety car up."

Although races in Canada are often marred by a high number of accidents, with the low downforce configuration and close proximity of walls catching out drivers easily, Webber has said he has no safety concerns about the venue.

"I think it's pretty safe. There are no real problems here. We have got some big stops, but you always try to think of failures, really - someone having a moment.

"Robert's situation last year was obviously extreme, and you have to cater for that - he lost his front wing, which folded below the car and took away his steering - but generally it's okay.

"If you have a brake failure into Turn 10 it should be pretty sweet, if you have some problems into Turn 1 that's probably the place where you're probably a little bit close on run-off, but I think you'd be fine. You'd go in pretty hard, but I think you'd be fine.

"It's OK around here. I think the track's pretty good."
