Is that how they handle it in the Chunnel?
As I understand it, no. The only thing that runs through the Chunnel is trains. Your cars get loaded on at one end and off at the other.
Basically like an underground ferry. In other words, Korea could be subject to millions of middle-aged Japanese woman swooning over Yonsama sites all over Korea. Korea will be raking in the tourist $$ and the cops will be busy handing out traffic tickets. LMAO!
