Track testing is expensive. Tire costs, transportation, consumable parts and testing time devour budgets. There is further increasing pressure as championship organisers seek ways to minimise costs through mileage limits or by restricting testing at designated tracks. Circuit testing can be inconsistent at the best of times with changeable weather and varying track conditions as well as a lack of availability. Restricted track time also prevents less experienced drivers from gaining circuit knowledge, driving the demand for accurate race simulation.
