To me, the "hellish landscape" is the NYC subway system (arguably the best in the US).
While I live in NYC and not LA, I'm a frequent visitor to LA. I'd gladly sit through LA traffic over riding the NYC subway. Sitting in my own personal, clean, climate controlled space, listening to music I enjoy.
I would gladly use Seoul's subway. I only grudgingly use NYC's (and nowadays, I bicycle as much as I can to avoid using it).
Just out of curiosity, have you ever been to Tokyo? I feel I've heard good things about its public transit but have only visited so briefly I didn't get much chance to use it myself.
FWIW many discussions that criticize any aspect of NYC’s subway system often gets shut down with “but we have 24/7 service and they don’t”. Personally, I feel 24/7 service is a contributing factor to the NYC subway’s problems.
