From GMMF1 is considering a radical innovation for 2011 in order to make overtaking much easier.Technical bosses of the twelve teams met at the Circuit Gilles Villeneuve on Friday, where it was agreed that the adjustable front wings will be scrapped at the end of the season.Instead, drivers will next year be able to adjust the angle - by a factor of 50mm - of the rear wings, meaning that straight-line speed can be dramatically increased when the cars are not negotiating corners.The intriguing twist, designed exclusively to boost overtaking, is that only chasing drivers will be able to adjust their cars' wings. A green light will shine in the cockpit when a car is close enough to the rear of his rival, thereby allowing the driver to trigger the rear wing button.The systems will not be available to drivers during the first three laps of a race, but the wings may be triggered after a safety car period."Why do we need KERS now? The overtaking wings will be enough!" Red Bull team boss Christian Horner joked to Germany's Auto Motor und Sport. "
