A vehicle includes an electronic control unit that includes a processor; and one or more processor-readable instructions; and an occupant detection sensor configured to output a signal indicative of a presence of an occupant. When executed by the processor, the one or more processor-readable instructions cause the vehicle to: record a route from a first location to a second location, and autonomously return to the first location from the second location using the recorded route based on the signal received from the occupant detection sensor.
