While lack of correspondence in driving simulation is an important problem, there is another aspect which is equally essential: motivation. People do not drive in a vacuum. they have some purpose for their journey, and for this they are prepared to take some risk. How do we simulate motivation ? One way is to award merit and demerit points for driving performance. All motivation cannot however be expressed in monetary terms, and there is no way of knowing whether a certain pay-off scheme represents the weight of real motives. In simulation experiments, subjects have no need to value time. To make the experiment more realistic, some sense of hurry should be introduced. For the paper by L. Harms, see C 6523.
