Absolutely it is better than not subsidising EV cars. No doubt. My issue is with the original comment painting this as something “barely any effort” implying that any country could do this. This was a unique situation and I’m glad that Norwegians chose to make themselves feel better about being an educated western petrostate bane on the planet by buying themselves EVs instead of feeding it to a king, ceo, sultan or emir.
Not every country has ungodly reserves of fossil fuels providing essentially free money. “Richer” is a bit silly - by raw GDP per capita, Norway has been one of if not the richest country in the world since the establishment of State Oil. Combined with not being a dirt poor monarchy ready to sell its resource extraction rights to Britain/America when the resources were found, Norway is nearly unique.
