Abstract: Systems and methods are provided for controlling a shared machine. The shared machine includes a mechanism that allows for an operational function of the shared machine to be controlled via a control system. A server system can process location information that indicates a location of the shared machine to determine whether the location corresponds to a non-permitted area. When the location corresponds to a non-permitted area, a command is generated to automatically place the mechanism in a first state so that the operational function of the shared machine is prevented from being enabled while the shared machine remains in the non-permitted area.
