We did a week-long driving vacation in Iceland a couple of years ago, driving around the whole island (in a gas-powered vehicle). It's a beautiful country with more sheep than people once you get outside of the few towns.
Iceland also produces almost all of their electricity through hydro and geothermal power, but almost everything else on the island has to be imported. They've been building their own electric charger network as well.
So you have:
1. A small island without much need to drive long distances
2. All the electricity you can use from renewable, green sources
3. Relatively high gas prices
4. An electric charger network allowing you to drive around the whole island in an electric car
it's a pretty good formula to promote EVs.
