As an EV owner in the USA (2021 Chevy Bolt EV), I do not recommend hugging trees and whales on your vacation as a good practice. Although probably everywhere other than the US has more density of charging stations, you don't need the complications when driving in strange places. And you don't want to spend hours charging when you want to be sightseeing. (My Bolt is a slow charger, but even with high-speed DC charging, it takes an hour to go from 20% to 80%, and the last 20% is very slow.) Up to half the chargers I approach in the US are broken (black screen) or will not start to charge, even when I have the right membership and credit card registered. Luckily places like Walmart may have ten chargers at Superstores.
I observed some chargers in Iceland where the car owner apparently had to bring his own cord (??)
