In addition, the track would begin opening on practice days around 12 noon, rather than the previous 9 a.m. Normally, the first few hours of practice were quiet and leisurely with few cars taking advantage of the track time. Thus they were deemed superfluous and excessive on resources and operating costs. This change was also introduced because it made logical sense to have drivers practicing on the track at the same time of day as they would be running in time trials and the race itself (theoretically it would better mimic the conditions encountered on those days).
