Getting pole is king

Being fastest in Saturday qualifying earns a driver pole position on the starting grid. This means he starts from the very front. Because overtaking is very difficult in a modern Formula One car, pole position carries an enormous advantage.
The tighter the track, the bigger this advantage tends to be. At tracks such as Monte Carlo or the Hungaroring, overtaking is close to impossible if the driver ahead doesn’t make a mistake. A driver getting pole position at either of these tracks may be considered to have the race half-won already.
In 2002, Michelin brought some super-soft compound qualifying tyres to Monte Carlo to enable its drivers to monopolise the front row of the grid. These tyres performed poorly in the race, as the soft compound led to rapid deterioration – but it didn’t matter. With track positioning all-important at Monte Carlo, Michelin-shod David Coulthard was able to keep Bridgestone user Michael Schumacher behind him throughout the race, even though Schumacher demonstrated that he could go at least 1 second per lap faster. Had he been able to lead from the start, Schumacher could conceivably have won by almost a lap. As it was, his qualifying position had consigned him to runner-up.
Not all tracks have such a lack of overtaking opportunities. At places such as Interlagos in Brazil or Hockenheim in Germany, you may see teams less concerned about pole position, especially if it means compromising their race strategies to achieve it.
