Unpleasant social interactions on the road can have negative consequences that affect driving safety. Any technological interventions to address these common occurrences need to be built on an understanding of the nature of social discomfort in vehicles. This paper contributes fine-grained empirical analysis and a proposed definition and categorization of the problem of social discomfort in cars to the HCI literature. We recorded nine families going on drives and performed interaction analysis on this data. Discomfort in the car could be divided into (1) local and full-body physical discomfort and (2) individual, social, or cognitive-load-related psychological discomfort. We define three strategies to address discomfort: contextual mediation, social mediation, and social support. We discuss three video excerpts in detail to illustrate the mitigation strategies. This work lays the foundation for the design of interactive vehicular systems for mitigating social discomfort.
