Nice one Peter W! Will look out for your shiny Tesla around the Shire
We have a plug-in hybrid - a Mitsubishi Outlander PHEV. With Aus still backwards in both charging infrastructure and in supporting fully EVs (which would do most people for >>90% of their driving), we needed to compromise. But even the ~50km EV range of the Outlander does perfectly for all my wife's commutes to Lucas Heights (a ~30km round trip). Virtually all our local driving in the Shire and Royal NP is 100% seriously fun EV. Our daily 'fuel' cost ~$1.20 for a full charge. We now fill the 40l petrol tank maybe every 2nd month, and get on average over 1000km for about 30l petrol (was 1700km the last time, maybe will be 900km on next fill because of a Blue Mountains trip). We rent our house (so no solar/battery), but buy 100% green electricity, and our total bill is still only ~$200/ month or less, charging is cheap! Petrol gets used for parts of longer drives, which are still efficient on the interesting part-electric drivetrain of the PHEV, with regen braking etc.
With the range of EVs rising quickly, and affordability improving quickly, the next one for us will almost certainly be a fully electric. Fewer moving parts, so EVs are much easier to maintain too, way easier than horses... With big chunks of the world's car manufacturing and markets going towards non-fossil fuel versions, Australia will not have a choice, but to follow, dragged kicking and screaming in to the 21st Century.
