Group characteristics. Participants’ usual speed on actual expressways with a speed limit of 100 km/h (A) and participants’ desired speed on expressways with no speed limit (B) were compared between participants who had high interest in sports cars and those who had no interest. In addition, to evaluate general propensities for stimulating and arousing experiences, between-group difference in sensation-seeking scale (SSS) score were also compared (C). Error bars represent the standard error. Single (P < 0.05) and triple (P < 0.001) asterisks indicate statistical significance. NS denotes that differences were not significant (P > 0.1).
