Point 4: as a notorious economics philosopher once said, "never get high on your own supply."
Along with not immediately blowing the petro money on a national level, Norway taxes petroleum products more heavily for local consumption than even its high tax neighbors - for a long time, gasoline was cheaper in Germany than in Norway, and Germany has high fuel taxes like pretty much every other European country (EU and non).
I mean it'll be more expensive, but since their economy is doing so well I can imagine it's still a lower percentage of people's incomes than in e.g. Germany; all is relative.
I mean cost of living is higher in cities but so is income. Usually. Sometimes.
It's a high enough petrol tax it prevented Norway from being full of gas guzzlers, and that it has been a disproportionately large EV market, despite being a) a giant oil producer and b) cold.
