Who the hell this J. Anderson is I care not.
You simply cannot draw an analogy between the road and our airspace system.
Damn right Your (lack of) risk perception is astonshing. You are quite content to know where other cars "are coming from"...save the small fact that they are inches from head on collision with you 24/7, quite likely poorly maintained, and driven by the unskilled, distracted, fatigued, tipsy, high or even neurotic... seen the figures on the dead and disabled?
Let you in on a little secret..60 knots or 500 knots, yous a gonner..
The fact that a unionised 1970s style, pencil pushing, public servant type airspace system has survived in Australia for so long, is no reason not to change it.
