I live on Jeju-Do: a South Korean island with a population of ~700'000. Half of the registered electric cars in all of Korea are on the island. Anecdotally, just driving down the road to work, every third car I see is electric. We've got electric buses, scooters, and bikes all over the place too. If only we could stop the pollution blowing over from China (not that Korea is innocent of polluting their own air.)
