yeah, once we get to 25% adoption (or something) we can talk about how badly EVs are hurting fuel tax revenue. in the meantime, jack up the fuel tax in a planned, regular way, and let the market decide :)
Many good things are unpopular. Shutting down coal mining operations is unpopular with miners. Staying at home to avoid spreading a disease is unpopular, but we have to do it anyway because it's important.
Switching to EVs is important for slowing down climate change, and should be incentived (incentivised?).
What those 2 Australian states did translates directly into accelerated Climate change and Coastal cities sinking.
