ABSTRACT
Cars are a profound form of technology that has woven itself into the fabric of everyday life so completely they have become virtually indistinguishable from it (Weiser, 1991). Cars are everywhere, they are ubiquitous, and as evidence of this ubiquity, it is easy to overlook exactly what cars and driving actually entail. For the driver, it means performing over 1,600 individual tasks, more or less successfully, in a highly complex road and traffic environment. What other device of similar technical sophistication is used so easily by so many individuals, each with widely varying levels of skill and ability, and possessing what can only be described as comparatively modest training? Not many.
