 The original bedouin guides were dropped in favour of extra drivers and the cars changed from daytime travel to driving in the cooler temperatures at night.The cars travelled in convoy, following well established routes that avoided wells or wadis where raiders might be hiding, and regularly checking on each other.The drivers became acclimatised to the conditions and were experts in the gilhooley maneuver where a car would spin several times, without turning over, on the polished mud flats that were part of the journey, before the driver regained control.
