20 In this case the aggravating feature, that is that the alcohol level exceeded 0.15, is established by reference to the presumption contained in s 52AA(3), but the level by which 0.15 was exceeded was not great. Second, while one may harbour many suspicions as to the length of the journey upon which the offender had embarked when the accident occurred, the evidence establishes no more than that she had travelled a relatively short distance. On the limited evidence available, it would seem that she had travelled at least a kilometre, maybe a couple of kilometres. The total length of the intended journey is unclear. There is no evidence of bad driving prior to the circumstances surrounding the collision and there is no evidence of a prolonged period of bad driving, probably only because the offender had just got in the car I might add. Nevertheless, there is no evidence of a prolonged period of bad driving leading up to the collision. As to the number of other road users who were put in danger, there is evidence from persons in two other vehicles. At 11.45pm on a Friday night, one would infer that there was some traffic on the road but again, in the absence of evidence, I would not infer that there was a moderate to high level of traffic activity on the road at the time of the accident. While other members of the public were put in danger, there is no evidence that there was a large number of such persons.
