Here's a bit more dialogue to suppliment DJ's post about the rule changes...

From Formula1.com:

The FIA’s World Motor Sport Council has agreed a number of significant changes to the Formula One regulations. Among them are a new single tyre supplier, aerodynamic revisions designed to boost overtaking, a ban on F-ducts, and the return of a 107% qualifying rule.

Pirelli will take over as the sport’s sole tyre supplier from 2011, following Bridgestone’s decision to withdraw at the end of this season. The Italian company will provide all teams with rubber for the next three years, in compliance with existing F1 sporting and technical regulations.

Under new moveable bodywork regulations for next season, drivers will be able to adjust the rear wing from the cockpit as soon as they are two laps into the race. However, the system’s availability will be electronically controlled and it will only be activated when a driver is less than one second behind another at pre-determined points on the track. The system will then be deactivated once the driver brakes. It will be available at all times throughout practice and qualifying.

In a move that could frighten one or two of the new teams, next year any driver not setting a qualifying time within 107% of the fastest Q1 lap will not be permitted to race. Stewards, however, will have the power to grant exceptions in extenuating circumstances, such as where a driver has recorded a suitable time in a previous practice session.

Several other measures have been brought in with immediate effect. Following the late-race confusion at Monaco, where Michael Schumacher passed Fernando Alonso, the safety-car rules have been clarified. No overtaking is allowed if the safety car is on track on the final lap.

And following the spectacle of Lewis Hamilton pushing his fuel-light McLaren back to the pits at the end of Montreal qualifying, new rules state that cars required to give a post-session fuel sample must arrive back in pit lane under their own power.
