Sure, increased rego works great. The per km thing is a bit creepy even if it's just reading the odometer, and as you say a bad deal for regional residents. It's also very viable to not own a car in the city. I don't have one. But in the country, what behavior are you trying to encourage? So that complicates things. It should probably be means tested too. I just object to the idea that EVs should be subsidized rather than ICEs punished. It puts the finger on the scale away from even better solutions like riding, walking or public transport.
