Leading Formula 1 drivers believe the Drag Reduction System (DRS) introduced in Formula 1 this year has been a huge success.
The device, which made its debut in the sport in the Australian Grand Prix this year, has helped boost overtaking numbers during the season. While some believe it has made overtaking too easy, Michael Schumacher is adamant that DRS has been a big success.
"To me it is obvious we have improved big time," said Schumacher. "We have had some exciting races. Look at Korea: if you think about the fight that Mark [Webber] and Lewis [Hamilton] had there, without DRS it would have been nowhere close. It would have been a normal and more traditional race. "In that respect it doesn't always work out perfect, but in general it has contributed a lot for some great racing."
McLaren's Jenson Button also believes the DRS has been a success despite having made overtaking too easy in some races.
"It has brought a lot to the races," Button said. "There are some instances when perhaps it made overtaking too easy, but there are always negatives with something like this. But the positives outweigh the negatives. It has brought a lot to racing, and you can get closer to the cars ahead. KERS has been important, too."
Williams driver Rubens Barrichello reckons the system has worked very well and is confident it will get even better next year now the FIA knows how it works.
"I enjoy it very much," said the Brazilian. "I think it has been incredible. I heard for 20 years that overtaking is not enough and now people are saying it is too much. People are saying it looks too easy, but I think it has been quite good. Sometimes it makes it too easy, sometimes not enough, but I think FIA can make it even better for next year.
"The new people that come to F1, they will still have to get used to the button. It is now easier as you get used to it, but the new guys will have to adapt to it."
