Technically, EVs aren't subsidized in Norway.
They are just extempt from our very high import taxes on cars. Other countries have some sort of system where you get a refund or rebate on the price, but you don't get that in Norway.
To illustrate the matter, take a VW e-Golf for instance. This is an expensive Golf in most places, but in Norway, because the ICE-Golf is taxed hard - the e-Golf is actually priced the same as the base model ICE-Golf. This means that the e-Golf is a bargain in Norway, as you get more standard equipment, it has more power and is even cheaper to run. Even if you are not really that into EVs and are just looking to get a car, that is a no-brainer.
If Norway didn't have those high taxes on ICE-cars, you wouldn't have seen that level of adaptation towards EVs as we have seen here in recent years.
I saw Bjørn Nyland's Youtube-videos too, and it is nice that they are building more chargers there. The problem has been that there can be far between towns, and to put a fastcharger in the middle of nowhere to enable charging inbetween proved hard to do. The roads and power grid can be miles apart, so you may have to build a small power grid to connect the fastcharger to the main power grid. That is a bit too expensive, and the fastcharger-operators decided to hold back a bit until cars with more range appered.
We are actually planning a trip to Northern Norway next year, but it will be using the diesel-SUV due to towing a caravan. Towing apart, I wouldn't have any problem taking the Leaf on a trip in Southern Norway though.
