Experimental Machine-Vehicles (M-Vs) are effective intervention tools to draw out knowledge and stories from a participating public. This is because M-Vs can create a dynamic multiple interplay of realism and fiction within the everyday performance of the city- the triangulation of Realism, Fiction and the Machine. The experience of realism and fiction exists in all aspects of life. Everyday we continuously engage with fiction and realism in deliberate and unconscious ways. Questions emerge regarding the nature and efficacy of the realism to fiction mix across a range of categories of experience. Although difficult to quantify at this point in time, it appears that different categories of activity are best facilitated by their own particular mix of realism and fiction. Further, the productivity of this mix appears to be maximised when the fiction component is at its strongest and simultaneously the realism experienced is also at its most dependable best. It also appears that there are a number of integrating or facilitating factors that influence the take up of this reality/fiction mix. These range from the generality of the environment in which the experience is taking place, to the specifics of M-Vs that are employed to generate actions and reactions. M-Vs can be used to facilitate greater knowledge (realism/data) and stories (fiction/unconscious) from a place/location, exposing, amplifying, intervening with and energising this reciprocal relationship between realism and fiction in the city.
