Does size matter? Spacious car cockpits may increase the probability of parking violations.

Cockpit design is a core area of human factors and ergonomics (HF/E). Ideally, good design compensates for human capacity limitations by distributing task requirements over human and interface to improve safety and performance. Recent empirical findings suggest that the mere spatial layout of car cockpits may influence driver behaviour, expanding current views on HF/E in cockpit design. To assess the reliability of findings showing that an expansive driver seat space predicts parking violations, we replicated an original field study in a geographically and socio-culturally different location and included an additional covariate. After controlling for car length, brand status, and car price, driver seat space remained a positive predictor of illegal parking. This suggests that the spatial design of vehicle cockpits may indeed have an influence on driver behaviour and may therefore be a relevant dimension to be included in research and applications of HF/E in cockpit design. Practitioner summary: In car cockpit design, ergonomists typically focus on optimising human-machine interfaces to improve traffic safety. We replicate evidence showing that increasing physical space surrounding the driver relates to an increased probability of parking violations. This suggests that spatial design should be added to the ergonomist's toolbox for reducing traffic violations.
