That's the point. Taking what you earn a and live with in Norway, and comparing it with other countries, due to massive subsidies (luxury-tax excemptions that usually apply to cars), a Tesla is an affordable option for an Norwegian looking for a nice car, while this is simply not the case for most other European countries.

The same applies to Denmark and Netherlands to some degree, btw. They just have other subsidizing programs.

E.g. VWs built in Germany are cheaper to import back from Netherlands to Germany, because Netherlands adds more tax to cars in general, VW thus reduces the price for this market, and you I individually don't pay the tax if you export.
