Vehicle sharing exists at the intersection between private cars and public transport. Such initiatives have multiplied over the last decade with growing citizen participation (Firnkorn and Shaheen 2016; Drut 2018; 6t-bureau de recherche 2019). Degrowth calls for more collective property and sharing (Jarvis 2019). Vehicle sharing offers the potential of wider processes of social-ecological transformation, propelled by two drivers of change. First, sharing vehicles means fewer vehicles will be needed in the economy to meet the same level of needs. The second lever is the demotorisation that it causes. Estimates of several case studies throughout Europe and Canada highlight a decrease in the distance travelled by drivers enrolled in a car-sharing system from 11 to 50% (Sioui et al. 2013, Meijkamp 2000). This chapter analyses to what extent the experience of the Autolib’ platform, a one-way station-based car-sharing system38 in Paris, can be a potential strategy towards degrowth. As such, the case study is necessarily limited to a Western context.
