Abstract
An experimental program to obtain quantitative data on how drivers utilize the performance and handling properties of their vehicles has been performed. Over 100 drivers participated in the experiment which consisted of driving through a specially-constructed proving ground. The results are analysed primarily in terms of the application of the maneuvering potential of teh vehicle used by the subjects. It is concluded that in addition to the analysis given in this report the extensive data accumulated in the program can also be applied to many other studies of driver behaviour.
