In this paper, we introduce a study on privacy setting acceptance of drivers for data utilization on vehicles, and factors related to privacy setting. This qualitative research is based on the factors extracted from former research on privacy setting acceptance for ICT services. That is conducted through questionnaires and depth interviews on connected car services. As a result, we show acquiring consent for privacy policy on data acquisition and service utilization, on and off switch of service utilization, and information acquisition timing are important factors for privacy setting acceptance. We also discuss specific opinions which are obtained by depth interviews.
