Great analysis. Although there is also the demand-side. We also have to reduce the demand side. Australia’s addiction to a certain pattern of mobility is hugely problematic anyway – so there’s a huge opportunity to reduce the overall demand by changing mobility (and its demands, like urban planning, retail, industry, work patterns etc), which would also make your numbers a lot easier to hit sooner. These are linked issues with multiple benefits, and the technology question is only one of them.
