Taxes on cars have always been high in Norway. If you buy a new car you pay about 40-60% in car tax and VAT. On electric you only pay the 25% VAT.
This means that E-Cars costs about the same as in low tax counties, while fossil cars costs up to twice as much.
As E-car sales have been higher than expected, the total is a tax reduction.
I don't know what impact this has on CO2 totals, but it helps quite a bit on the air quality in cities. Particularly in the winter, when the fumes tend to get locked in over the city.
In effect, that's exactly what I said: the people who can afford property with off-street parking have an opportunity to save money while those who don't, don't.
Poor people being penalised for not being rich enough to afford cool stuff.
Not keen on that as a paradigm.
