During this time the vehicle is unavailable and cannot be reserved or rented by other users. The vehicle status in `vehicle_status.json` MUST be set to `is_reserved = true`. If the value of `default_reserve_time` elapses without a rental beginning, the vehicle status MUST change to `is_reserved = false`. If `default_reserve_time` is set to `0`, the vehicle type cannot be reserved.
