V8 Car Racing

I love V8 supercar racing, I really want to follow, but I have a problem ... I do not understand the rules and im not entirely sure what its about other fast cars to assign laps around a track. As in, why they can not slide the power better than the slowdown in second gear, then take off again ... and why they may not burn out early to get a further boost. Just the essentials. I tried Google but got nothing.

Power sliding looks cool, but it is slow. lateral movement is wasted motion. As for fencing, I'm not familiar with this series but they may use traction control. Again, burnouts look cool, but they are slow. Wheelspin is a waste of energy, not to mention very degrading for the life of the tire.

The practical answer is that the driver can use any style he / she wishes, rules (and the owner of the car) permits. However, a technique that works for one may not for another.
