As a result, it is not surprising that some shared vehicle drivers, for instance, report that the biggest obstacle to driving an EV in the network is a lack of rapid charging stations in areas of high mobility demand (e.g. downtown centres or airport queues). The need for time-consuming charging, often multiple times per day, for example, reduces drivers' availability for offering rides and earning fares. Drivers report that range anxiety can lead them to decide to cancel trips.
