This paper presents a driver motivation theory. This theory assumes that: (1) drivers generally try to maintain a speed they enjoy; and (2) that they accordingly try to avoid obstacles that force them to choose another (lower) speed. The main argument presented is that drivers who enjoy a somewhat faster speed than the average driver, will relatively more often be obstructed by other road users. Accordingly, these drivers will be more concerned with predicting other road users' behaviour than the average driver. This preoccupation with predicting other road users' behaviour is primarily motivated by these drivers' goal of maintaining a desired speed. However, it is argued that the information they obtain in order to reach their goal has safety as a by-product. The theory is tested using survey data on both driver behaviour and self reported accidents.
