Qualifying itself acts as a sideshow where the drivers have a chance to prove themselves in a certain aspect of racing - Sheer speed. Every driver aspires to this 'prize' . There will be kudos for being the best at other aspects ofcourse but the 'fastest' guy is the one, Villeneuve, Senna, Clark etc
The race is very important, and as long as you can finish high up each race sheer speed is not the end all and be all, certainly not this year, but one must be able to beat others in the actual race even without speed.
I reckon any driver would rather have the problem of starting first and going backwards than starting lower and having to move forward
