Note that Euros drive about half as much as Americans, and I’ll bet the average trip is half the distance too. That and the high gas prices (more than double those in the US), make EVs much more attractive there.
The Leaf is relatively affordable, though I believe Nissan loses money on every one.
Back in 2010, Nissan said that it would initially lose money but that the Leaf would be profitable by year three. Now, Nissan is selling the Leaf in new markets. Especially in Norway, where electric cars make up 12% of new cars sold despite the cold weather there.
