The automotive zeitgeist is unmistakably steering towards electric and autonomous vehicles. This shift challenges the traditional fiscal structures, predominantly reliant on fuel-based levies. To address this, Australia is meticulously crafting frameworks for road-user charging. Such systems, nuanced in their approach, might incorporate variable pricing based on usage, time, or congestion levels. The potential introduction of maximal parking ratios represents another facet of this paradigm, ensuring urban spaces are optimally utilised and revenues are sustainably generated.
