That is because people who drive on a public street are enabled and encouraged to drive at speeds that would be quite dangerous were it not for the fact that the vast majority of other drivers will also act in accordance with the letter and the spirit of regulation 65. As a small contributor to a complex system of social management, regulation 65 really tells the drivers of New South Wales that if they want to drive on the road, this is how they should go about it. Some laws do this without imposing criminal sanctions. Thus, the Wills Act describes how a person wishing to make a valid will should go about the task. Failure to comply does not result in a fine, but intestacy.
Some laws are concerned with compliance itself.
Indeed, questions of compliance are as old law itself. The way in which a society deals with the execution of its laws, including its use of army and police, is of the essence of the way we perceive that society itself. Recent events to our north prove this truth. As I indicated at the start of my remarks, good laws without good compliance serve little or no purpose. Indeed, the distance between precept and practice brings the whole system into disrepute.
