Suspicious minds? - users' perceptions of autonomous and connected driving

In this article, the public perception and acceptance of novel vehicle technologies - autonomous driving (AD) and connected driving (CD) - is investigated. Following a multistep empirical procedure, we explore participants' cognitions towards AD and CD. Therefore, a questionnaire study was run in which the perceived benefits and barriers of the technologies were evaluated by 443 participants in a wide age range (18-76 years). In addition, we took a closer look at the impact of user diversity (gender, age, need for privacy, control, risk taking tolerance and technical self-efficacy) on the evaluation of both driving technologies. Finally, cluster analyses were used out to identify evaluation profiles in both benefits and barriers, respectively. Overall, CD is seen significantly more positive compared to AD. With increasing risk taking tolerance and technical self-efficacy, the perception of the benefits was higher. In contrast, the perception of barriers in novel vehicle technologies was independent of personality factors and attitudes. Here, privacy and data protection issues were seen as key disadvantages. The findings can be used to develop timely and individually tailored public information and communication strategies for automated and connected vehicle technologies.
