Several studies have focused on drivers\u2019 perceptions related to the use of AVs, exploring the \u201cacceptability\u201d and acknowledging that this is not an individual process [1]. Acceptability is constructed in a particular socio-organizational context, whose underlying conditions pose different determinant factors of usage [2].  The debate on the acceptability vs. acceptance of technologies requires the assumption of a psychological standpoint: \u201cacceptability\u201d is a cognitive representation that users have before using technology, i.e., it is an a priori phenomenon [3], whereas \u201cacceptance\u201d is an a posteriori pragmatic evaluation, inasmuch as it is \u201csituated\u201d in a real activity [4]. Hence, the \u201cacceptance\u201d is associated with an \u201coperative representation\u201d developed in and by the action.  Bearing in mind such conceptual frontiers between the two constructs, it should be noted a point in common: they are subjective representations related to different sociodemographic characteristics and inscribed in specific conditions (e.g., driving preferences, benefits\/concerns associated with AVs). Considering the fact the use of fully AVs is not yet possible, the study we present sought to explore the acceptability of AVs in the frame of a Portuguese research project. The AUTODRIVING project combines an extensive survey on the viewpoints of representative groups of drivers with a driving simulator study to evaluate driver-vehicle interaction under automated driving scenarios. A self-administrated questionnaire was developed aiming at exploring Portuguese users\u2019 representations about the AVs, considering their expectations (e.g., the possibility to perform secondary tasks during automated driving), concerns (e.g., loss of control over the driving), levels of trust, and the benefits and risks users most associate with AVs. 500 portuguese participants (49.3% female), aged 18-81 years (M=42.16, SD=41.39), responded to the questionnaire.AVs acceptability was assessed through four items: \u201cconsider to using a fully AV\u201d; \u201cwould prefer a fully AV to a non-automated vehicle\u201d; \u201ccomfortable with family using an AV\u201d; and \u201cconsider using a fully automated bus\u201d.A two-phase cluster analysis approach was used to identify patterns of AVs acceptability. Firstly, a hierarchical method was used to identify possible appropriate solutions for the number of clusters. Secondly, the suitability of the different solutions for the number of clusters was tested with non-hierarchical cluster analyses. Four distinct clusters were identified and named based on the pattern of acceptability and their characterization regarding demographics, self-perception of technology use, driving and AVs experience. The clusters we found are: - Resigned: AVs are convenient\u2026 but are they safe? These participants consider using AVs and a fully automated bus more than average, but don\u2019t prefer AVs to non-automated vehicles and are less comfortable than average with family using an AV. - Suspicious: AV\u2026 maybe not, we still need to know better this technology These respondents present all acceptability variables slightly below average, but a predominance of automated bus rejection; - Enthusiasts: AV, certainly yes, and benefit to its full potentialParticipants whose acceptability is above average for all the variables; this group has a predominance of higher income participants, that live in predominantly urban areas, are willing to experiment with new technologies and would like to perform all secondary tasks while driving (e.g., reading); - Objectors: No AV\u2026 we want to keep driving pleasureRespondents who score below average in all acceptability variables; this cluster has a predominance of participants 50 years old or older, who live in predominantly rural areas, prefer to wait some time to try new technologies and whose car doesn\u2019t have any driving aid system.These quantitative findings were complemented with 7 focus groups, involving both professional and regular drivers, in order to set a \u201cuser model\u201d that could be mobilized in the current debate about the conditions that may contribute to the acceptance of AVs.
