The article describes an approach to designing an ideal human-car subsystem. Ensuring road safety in the modern world is a pressing issue. The number of people injured or killed on the road (with the goal of ensuring zero mortality) is still very high. The drivers’ role in creating the prerequisites for road accidents is also extremely significant, but neither abandoning motor transport use nor radically reducing the drivers’ number among the population of large cities seems possible and reasonable. However, turning to psychological approaches and methods for solving safety problems can bring the long-awaited effect. The paper speaks about using the resource approach to designing ideal human-car subsystems (from the viewpoint of reliability) which are in turn part of the driver-car-road-environment system. To design such systems, it is necessary to combine the capabilities of psychology in the field of psychodiagnostics of the driver’s professionally important qualities, the resource approach (which involves using three types of resources by the subject, namely intra-individual, inter-individual and extra-individual), as well as the capabilities provided by the technical characteristics and technical systems of modern vehicles. The article demonstrates an approach based on which it is possible to propose solutions for supplementing, duplicating or limiting the driver’s capabilities using extra-individual resources (technical systems and technical characteristics of the vehicle). The paper presents data of an empirical study conducted based on the experts’ opinion in the transport industry. The authors make conclusions regarding the prospects of the proposed approach.
