What are the odds that the lorry in question was doing 50 and he had to do "just over" 50 to overtake it. 50mph limits usually seem to be in areas of pretty poor visibility, what the hell was he doing trying to overtake anyway?
If the lorry was a big'un then it would have been legally restricted to 40mph on a single carriageway road anyway. Surely you're not suggesting that the driver of an HGV might have been speeding ;-)
