Exploring end-user experiences: Self-perceived notions on use of adaptive cruise control systems

This paper explores end-user experiences of adaptive cruise control systems. A qualitative approach has been applied and data has been collected by means of focus group interviews. In total the study consists of three focus group session with five to seven participants in each. Themes explored include interaction between user and system, functional limitations and trust, and system effects on driving behaviour. Key findings include reported driving behaviour changes as, for instance, an increasing tendency to stay in the right lane and user conceptions about system functionality regarding which can be concluded that end-users of adaptive cruise control carry rough mental models of the system
