Abstract The transport policy discourse posits Shared Autonomous Vehicles (SAVs) as a more sustainable solution for the implementation of road automation technology. A successful implementation of SAV services strongly depends on being able to meet user's needs, as well as responding to their expectations. For this reason, the public has a central role in the definition of appropriate and realistic policies for the design, regulation and adoption of new automated mobility services. However, whilst there has been considerable attention to individuals' attitudes towards road transport automation, few have applied participatory or co-design methods to help define new SAV services. Moreover, most of the existing studies have also been hypothetical rather than examining vehicles in real service settings. This paper addresses these imbalances through reporting a two-stage research initiative. Initially a local shared automated vehicle service (LSAVS) concept was examined in a co-design workshop (Stage 1), leading to the development of a conceptual framework for social acceptance. This was then applied (Stage 2) in qualitative empirical research into the experiences of participants who rode in two different live prototype LSAVS. It was found that social considerations such as equity in access to mobility services, social inclusion, environmental protection, and concerns about control over interpersonal interactions emerged as strong acceptance factors within participants' construction of the conceptual services and responses to exposure to actual services. However, broad socio-political aspirations beyond transport policy were also important. It is concluded that achieving high levels of social acceptance where these utopian expectations meet commercial realities and public-sector constraints will be a major policy challenge facing any attempt to introduce an LSAVS with strong sustainable mobility credentials.
