Fully autonomous vehicles provide an opportunity to improve current transportation solutions; both for drivers and for people unable to drive. In this paper we present the preliminary results of a study aiming to understand user needs and expectations for autonomous vehicle interfaces. We found that users expect a different type of information to be fed back to them depending on whether the vehicles are privately owned or shared. The results of this study will be confirmed by further work and contribute to the development of a baseline fully autonomous vehicle user interface.
