Who would've thunk, economic incentives help!? Sadly in many other places the deciding economic incentives are the ones the politicians get from the oil and ICE car industry.

If you want to know what Norwegians really think about the tax, make it optional and see how many people pay for it.
If you want to see what Norwegians really think about paying for things in stores, make shoplifting laws completely optional, and replace cash registers with tip jars, and see how that works out.
Given their relatively contribution to the total global production and OPEC's supply management to control prices, it is unclear if a halt in Norwegian oil sales would raise prices significantly enough to matter. There is an argument to be made that is is better for Norway to capture those profit and invest them into the research we need to reduce oil dependence and sequester CO2.
I don't think that the electric car adoption is purely driven by environmentalism. Norway has extremely cheap energy that makes electric cars much more economically attractive.
On an individual level basically no one in Norway buys an electric car due to environmentalism. It's 100% an economic decision. Buying a new gasoline powered car today in Norway simply doesn't make financial sense no matter how you look at it.
This is essentially performative environmentalism from them. Still, it will help other countries by throwing up unforeseen problems in all-electric ground transportation, and some solutions.
