On the other end of the scale are the races like Shanghai, Yeongam and Spa. DRS created an added spectacle in these races that they would otherwise have been missing. Sebastian Vettel
would have been held up by Nico Rosberg
at Spa, costing him a victory, while in Korea, Button and Rosberg had a magnificent see-saw battle thanks to DRS. Button passed, Rosberg re-took in the zone only for Button to pass once more in a fantastic manoeuvre on the next lap. Shanghai was possibly the most exciting race of the season thanks to the tight controlled racing and spectacular overtakes by the likes of Kamui Kobayashi
and Webber on his way from 18th to third.
The main criticism of DRS is that it is 'artificial' and makes racing more of a video game. While there is certainly room for improvement, practically any design rule can be considered artificial. From KERS to the new, intentionally mediocre Pirelli tyres, we're seeing more limits on design than we did previously, but we're also seeing more battles between front runners than we would have otherwise.
With all this in mind, when considering DRS as part of F1, it should be remembered that it's still being developed. [F1 race director] Charlie Whiting has often said that he is experimenting with the set-up, cautiously balancing the racing spectacle, safety and software limitations of the system.
2012 will see the system revised again, with Whiting predicting that the Melbourne GP could see two DRS zones, with only one sensor zone, giving a driver two chances at passing.
As the system evolves and is refined we should see fewer instances of slower cars holding up faster ones after pitting, rewards for the aggressive drivers and a lot more wheel-to-wheel overtaking, which can only add to a spectator's enjoyment of the races.
