Vehicles, the carriers of representational content, are an important, if somewhat undertheorized, posit in cognitive science. In this paper we argue that generating and maintaining representational vehicles is not a trivial problem, even more clearly so when we are dealing with cognition in complex systems such as brains, or brain-body-environment aggregates. We discuss various vehicle-building operations and strategies that can be applied to complex systems (such as underutilizing and enlarging
