2011 'proximity wing' rule not set in stone

Plans for adjustable 'proximity' rear wings next year are not set in stone, according to FOTA chairman Martin Whitmarsh.

The idea, giving chasing drivers the ability to reduce drag and therefore better mount overtaking moves, was championed by the teams association and recently rubber-stamped by the FIA.

But there has been some opposition since the announcement; primarily by those who think it is an unnecessary and artificial ploy, and also those who are concerned about safety.

"We will see whether people are convinced by it or not," said Whitmarsh, also the McLaren team boss.

The Briton admitted the proximity wing was developed due to "fan-based pressure" to improve the spectacle of overtaking, but said it is not certain the innovation will actually debut.

"I think we have got to do a little bit more work on deployment and the sporting regulations that accompany it, and if we get that right we'll give it a go," said Whitmarsh.

He confirmed that if "it detracts, isn't right, it's easy to take it off".

"But let's have a look at it; it's a bit of an experiment."

Former grand prix driver Anthony Davidson is not confident the wings will ever be seen in action.

"I think teams just like to see what people like us think about it before it actually gets put forward," said the BBC radio commentator.
