    Lists all occupant (= driver + passenger) zones available in the car.
    Some examples are:
    <item>occupantZoneId=0,occupantType=DRIVER,seatRow=1,seatSide=driver</item>
    <item>occupantZoneId=1,occupantType=FRONT_PASSENGER,seatRow=1,seatSide=oppositeDriver</item>
    <item>occupantZoneId=2,occupantType=REAR_PASSENGER,seatRow=2,seatSide=left</item>
    <item>occupantZoneId=3,occupantType=REAR_PASSENGER,seatRow=2,seatSide=right</item>

    occupantZoneId: Unique unsigned integer id to represent each passenger zone. Each zone
                    should have different id.
    occupantType: Occupant type for the display. Use * part from
                   CarOccupantZoneManager.OCCUPANT_TYPE_* like DRIVER, FRONT_PASSENGER,
                   REAR_PASSENGER and etc.
    seatRow: Integer telling which row the seat is located. Row 1 is for front seats.
    seatSide: left/center/right for known side. Or can use driver/center/oppositeDriver to
              handle both right-hand driving and left-hand driving in one place.
              If car's RHD / LHD is not specified, LHD will be assumed and driver side becomes
              left.
