39 In that connection, the following observation of Street CJ in Murnin v R (Court of Criminal Appeal, 16 August 1985, unreported) remains pertinent:
"A motor vehicle is a potentially dangerous - indeed lethal - machine. Those who drive motor vehicles on public highways, as do the overwhelming majority of members of our community, must inevitably accept that if they drive those potentially lethal machines dangerously and occasion death or grievous bodily harm, then the criminal law will exact from them a penalty appropriate to the degree of criminality which the whole of the circumstances disclose. The Legislature has always placed a premium upon human life and the taking of a human life by driving a vehicle dangerously is by virtue of this particular section to be regarded as a crime of some seriousness."
40 These observations have been reaffirmed in this Court many times. As Sully J observed in R v Hall [2001] NSWCCA 202 at [66]:
"When…the crime to be punished is not the crime of dangerous driving causing death, but the crime of murder where the murder weapon is a motor vehicle, then the foregoing statements of principle are strengthened even further, and must be applied accordingly by a primary sentencing Judge."
41 His Honour also observed that the use of a motor vehicle as a weapon is all too frequently committed by young offenders with previously good character, and, accordingly, that general deterrence is a paramount consideration in framing an appropriate sentence.
42 Since I am satisfied that the offence is within the mid range of offending of its type, I am required by s 54B(2) of the Sentencing Act to impose the standard non-parole period of 20 years unless I am satisfied, by reference to s 21A of the Sentencing Act, that there are reasons for departing from it.
Are there reasons for departing from the imposition of the standard non-parole period?
43 It was submitted on the offender's behalf that various mitigating features, in combination, justified a departure from the standard non-parole period. It is said that he has good prospects of rehabilitation given his age, that he was of prior good character and that the nature of the offence and the circumstances in which it was committed make it unlikely that he will reoffend. I am not satisfied on the evidence before me that these matters, either individually or in combination, operate to mitigate the objective seriousness of the offending.
44 The material tendered on the offender's behalf consisted of a report from Dr Andrew Walker, a senior staff specialist in forensic psychiatry with the Hunter Mental Health Service, a Probation and Parole Service pre-sentence report and testimonials from the offender's friends and family.
