The proportion of participants who selected the EV over the petrol or hybrid vehicle was higher in areas in which EVs are more prevalent than those in areas where they have a low prevalence. This was true for both those who received the social norms message, and those who did not. The social norms message had a similarly positive impact on participant’s EV choice regardless of the EV density in their area. This suggests that social norms messaging could be useful to increase uptake of electric vehicles regardless of direct level of exposure or peer effects.
