The objective of this project was to combine naturalistic and experimental car studies with an ethnographic approach to investigate user experience of automated driving on public roads, and to study how the increased intelligence in and around the automated car affects trust in the automated car. Several studies have been conducted within the project, using various as well as combined research approaches. The main focus has lied in what makes people trust the automated car and how they experience and behave during automated driving on real roads. The literature, as well as the research conducted within this project point towards that trust is continuously ongoing and that it develops and changes over time. Trust is affected not only by the actual experience of automated driving on real roads, but also experiences with technology in everyday life situations.
