The paper proposes and develops an original concept, dormant vehicles, which refers to vehicles that are stationary while waiting to be used again, such as current parked cars. The concept involves several types of vehicles (cars, bikes, vans, automated vehicles), durations, temporal locations and rates of recurrence that, with the emergence of new mobility futures, would have diverse forms with significant implications for land use, space and place. New forms of dormant vehicle include shared electric vehicles, dock-less bikes and delivery vans that besides parking would present new in-between use situations such as dropping-off, picking-up, delivering, charging and awaiting repair. The paper highlights that without thinking clearly about these aspects of the future, plans for sustainable, smart cities could fall into a similar trap as in historical versions of automobility and parking, that is, of overlooking dormant vehicles and the ways they shape and are shaped. Rather than parking conveniently disappearing from cities, it is instead likely to change in various respects. The paper sets out to put this research agenda at the forefront, drawing on social theories of practice to propose and develop this new concept, highlighting its potential contribution to urban futures thinking. Ultimately, the paper argues for inverting urban mobility futures to identify the new forms of dormant vehicles associated with them, and consider their implications for land use, space and place.
