Unless the "safety" car was driving much much too fast and/or there was very thick fog.
Maybe the tug was hooting a warning and the safety driver turned around to wave back without realising there was an aircraft attached ?
First light was 18:38 UTC, sunrise was 6:07am so it was dark o'clock. Shift changeover normally occurs around 5am so maybe they were rushing back to base, or medical episode. Hope the driver is OK.
