Ok maybe a little bit of hyperbole but not that far off the mark, fiscal policy in Australia is dominated by preferential treatment for the boomer generations finances.
Ideally we would provide incentives in the form of a refund for all vehicles below a net carbon value per km (so including plugin hybrids, etc) that are priced below a given value, say $40k AUD or something, whatever is actually affordable mid-range car (not sure about specific numbers).
The idea is that hybrids are probably going to be at a disadvantage unless they are insanely efficient, BEVs will need to bring prices down to qualify for the incentive and generally speaking we end up with drastically more efficient -and- cheaper cars as a result.
However it's also not a great look if all the boomers are buying 911s instead of Model S/X etc so may as well drop the luxury car tax for full BEV vehicles so gas guzzlers are at a disadvantage across the spectrum.

> its the sane in britain - if you earn $200,000 income-tax-free means 50% off, but if you earn $20,000. it means like 5% off
For SS schemes the person earning £20k would be paying a marginal rate of 32%. Most people earning more than this have a marginal rate of 42%, then frankly the figures get complicated to explain but it's a very small minority of people that hit those levels.
Not exactly true. Besides company car tax (BIK) benefits, electric vehicles are exempt from vehicle excise duty, which can save up to £4000 over the first 5 years of vehicle ownership. They are also exempt from congestion charges, low emission zone charges, etc, which can save thousands more. There's also no fuel duty on charging an EV, you only pay 5% VAT on electricity if charging at home, many local councils offer discounted parking and/or charging, and there is a grant available that pays 75% of the cost of installing a home charger.
I'm leaning towards the refund since it effectively gives everyone the "same final price"
