Its all a matter of cost, jobs, industrial lobbying, policting etc etc- as with EV's, energy efficient homes are expensive - my original post was making the point that I doubt EV's will be both economical and popular in Australia before 2040 that is for the majority of the population, but I'll probably be dead by then or not driving as someone has taken away my license, but there again will I need a license with a self driving car, anyhow so I'll stick with my ICE for the foreseeable future
