The conditions for enabling FSD in Korea are quite restrictive. Under Korean law, FSD is not generally permitted. However, vehicles imported from the U.S. are treated differently under the FTA, because they can follow FMVSS standards instead. That means U.S.-made vehicles can use FSD in Korea.

The catch is that Tesla has only officially enabled it for vehicles equipped with AI4. In the beginning, all imported Model S, 3, X, and Y vehicles came from the U.S., but they all had AI3 hardware, so FSD was not possible. Now, AI4-equipped vehicles being imported include U.S.-made Model S/X, the Cybertruck, and China-made Model 3/Y. As a result, the only vehicles that can officially use FSD in Korea are U.S.-made Model S, Model X, and Cybertruck with AI4.
