The present disclosure is directed to a modular autonomous-vehicle interior. In particular, an autonomous vehicle can comprise an interior comprising a plurality of different and distinct regions. Each of the regions can comprise one or more mechanical interfaces associated therewith. The autonomous vehicle can also include, for each of one or more of the regions, at least one modular interior unit comprising an interior element and a base mechanically interfaced with the interior via the mechanical interface(s) associated with the region.
