I can see that you have sand in your underpants about getting infringements for breaking the law. It is obviously uneconomic to have very expensive police officers enforce traffic crime when automated cameras are so effective. What you are really arguing for is individual exceptionalism for rich people to violate speed limits.

It isn't a "social experiment" to deter crime, and calibrating punishment to have an actual deterrent effect has a long precedent. If it is "nanny state" policy to set speed limits that penalise repeat offenders and hoons in high powered cars, you will find it has broad community support.
