Assuming that there is a totally free market in the first place. Norway is a socialist country. All public transportation (and infrastructure) is owned by state or county. That will change somewhat soon, as private companies will be allowed to compete with the national train company. However, the state will still own the train cars and the tracks.

Public transportation is promoted way more than EV. And special EV privileges will disappear over the next couple of years. EV, hydrogen and hybrids will still be cheaper due to us taxing emissions, however.

Not to indicate that Norway doesn't have a free market, it mostly does. Exceptions are alcohol and public transit (state secured monopolies).
