Interesting stats here:
Electric vehicle snapshot August 2021 (particularly that Tesla has a 75% market share in QLD. The M3 has 55% market share alone).
I feel like the vehicle price cutoff is too low and QLD is way to small to even marginally "influence the industry" to build smaller / cheaper EVs. Costs everywhere are going up, pretty much all BEV vehicles are on massive waitlists and so I don't see any manufacturers rushing to put out a cheap BEV while they can sell as many of the higher priced ones as they can currently make.
Personally I'd rather they use the money to build out charging networks. I still personally feel like 'range anxiety' is one of the bigger concerns (especially amongst my friends / family). The reason we don't have range anxiety in ICE vehicles is because we know there will be a petrol station wherever we go... make charging facilities the same.
