OK, so Spa-Francorchamps with a 2005 car on track looks great, but this is the perfect picture of a qualifying session that year. Prior to the three-stage knockout system being introduced in 2006, F1 qualifying consisted of one car at a time on track for one lap. Simple and filled with pressure, but it did not excite TV audiences who waited a long time watching cars they were not always interested in, waiting for a potential fight for pole.
