Captain Caveman 76:
What a lot of people don’t seem to appreciate is how disorientating it can be seeing tail lights on unlit motorways.
I really do think that having done lots of this type of car driving for fun before I started night trunking really sharpened up my levels of alertness and advanced perception of and dealing with hazards and speed differentials,on unlit motorways.While seeing examples of the potential consequences of getting it wrong,as seemingly in Wagstaff’s case 
,looking back I’m very thankful for the grounding that those roads and speeds gave me. 
Watch the lane change at 1.15 and the tail lights ahead which he’s basing that lane change on and which he doesn’t actually reach until 1.27.That’s advanced perception and that’s the point when you need to make the call to either stop for a stationary hazard or just overtake a slower vehicle in lane 1,no ifs no buts no excuses.
