This situation nearly happened to me just a couple hours ago - thankfully I was maintaining a proper distance from the semi truck in front of me as it swerved left out of the lane - otherwise I would have had no chance to notice the car going <15mph with no lights on, in the middle of the night, on a 70MPH interstate.
