INRETS (France) has carried out research work to determine to what extent drivers make use of the dynamic performances of vehicles in the course of everyday driving. A sample of drivers from varied backgrounds drove over a set distance, including all types of road infrastructures, at the wheel of a specially instrumented vehicle. The data analysis shows that longitudinal and lateral accelerations are low in everyday driving. Significant inter-individual variations in the behaviour of drivers, when at the wheel of the same vehicle, over the same stretch of road, were also revealed.
