I emailed VIc Roads regarding the 3km/h issue as well as the ridiculous fines, and slow speed limits. The response was as follows:
I refer to your recent email regarding road safety. I apologise for the delay in replying.
The reduction in the default urban speed limit from 60 km/h to 50 km/h was introduced to reduce road trauma particularly for pedestrians. The lower speed limit has resulted in a 13 per cent reduction in casualty crashes for all road users, and a 46 per cent reduction in serious and fatal crashes involving pedestrians.
The posted speed limit is the maximum speed at which motorists may travel under ideal conditions. Depending on the level of traffic activity, road and light conditions or weather, motorists may need to travel at a lower speed.
The new 50 km/h default urban speed limit applies to local government roads. Some local councils chose to retain 60 km/h on some of their busier
roads. If you wish to discuss the speed limit on any particular local road, you should approach the local council.
Recent research by Monash University Accident Research Centre found that Australia still has a high urban speed limit compared to many other developed countries.
Speeding is a major contributor to trauma. Research both in Australia and overseas shows a strong relationship between speed and road safety. Higher vehicle speeds are associated with longer stopping distances and greater
impact forces, which result in an increased risk of crashes and
crash severities. The research shows that even a small increase in speed can increase crash risk significantly. In a 60 km/h zone, for example, the research shows that for every 5 km/h increase in travel speed above the 60
km/h limit, the risk of crash involvement doubles.
The onus is on motorists to travel at or below the speed limit.
inevitably involves periodic checking of the speedometer to
appropriate travel speed is maintained. This is a fundamental
of the driving task.
The management of speed and reducing the incidence of speeding is a major component of arrive alive! Victoria's Road Safety Strategy 2002 - 2007, which aims to reduce the road toll by 20% over this period. This Strategy

Thank you for your interest in road safety.

OK NOW MY THOUGHTS
Does he want to change his views now after seeing recent statistics? And if Safety is a concern, have a look at towing regs, where currently a Falcon is allowed to pull 2300kg, Sorry thats bulldust, you need an SUV to pull something that heavy safely.
Next, I was talking about Interstate speed limits, not urban speed limits. How about comparing speed limits to countries such as Canada, USA, and other large modern countries rather than England, where roads are windy and narrow and the country is small and very populated.
The rest of the bullcrap is pretty self-explanatory.
