Watching the racing may be confusing for the uninitiated but it is generally useful at the start of a race to keep tabs on the low grade drivers ('white tops'), since they are prone to making mistakes, as well as the star drivers ('red tops') who start at the back of the grid. During these opening laps, drivers will jostle for position as they establish who has the best pace on the track. Star drivers will generally make their way through the field using a combination of speed, guile and contact while some of the lower grade drivers may 'break away' at the front. As the number of laps remaining counts down, excitement will build as to whether any breakaway cars can be caught and whether they are prepared to vigorously defend their positions against the higher graded drivers, especially if this culminates in an opportunity for a 'last bender.'
