Mobilities are being greatly reshaped in order to respond to contemporary challenges, such as automobile dependence, environmental pollution and so on. Mobilities performed by Autonomous Vehicles (AV), or driverless mobilities, will play a leading role in this process due to the vast array of new possibilities they may bring. In particular, this technology will bring a sharpdecrease in the overall cost of mobilities system, including their spatial, social, environmental etc. negative externalities, and notably contribute to their optimization. However, since their implementation is at a rather immature stage, many aspects including, but not limited to their potential effects, technological readiness, legal issues, ethics and societal acceptance are still largely undiscovered. Aim of this project is to elaborate on the future modus operandi of driverless mobilities, as well as to identify which are the supportive driving forces and the challenges in their implementation. Examination of two cases where driverless mobilities have been practiced, in Aalborg, Denmark and Trikala, Greece, pointed out a strong impact of three elements in making driverless mobilities. Safety goes first. Embodiment of AV into existing mobilities practices will be impossible if actual and perceived levels of safety are not high enough. Then come two factors of equal importance, namely proof of usefulness and perception of people towards them.
