I live in Denmark. I still see a rapidly growing number of electric cars on the streets. It is just smaller, less expensive electrical cars that take over (Renault Zoe, WV e-UP, Nissan Leaf). I would venture to guess that Danes don't want to spend more than X kroner on a new car. And the Tesla price point broke that limit when the tax discount was removed.
Pronouncing the electric car uncompetitive over this is an exaggeration.
The decline in growth is entirely the result of the huge import tax:
> electric car dealers were for a long time spared the jaw-dropping import tax of 180 percent that Denmark applies on vehicles fueled by a traditional combustion engine.
This article is only looking at growth rates, not total sales by cost or by market position, so it wouldn't be a useful comparative metric anyway.
If anything, what it indicates is that they'd sell 10x more cars (both electric/gas) if it wasn't for the tax.
