Yeah, if you're not used to it, I can see that being a problem. I didn't take the trains during the major commute hours, so I probably dodged that experience on my own trips around. Not sure how I would have taken it, but yeah, I probably wouldn't have enjoyed the experience either (probably typical American opinion on that though).

That said, it definitely feels like one of those "no one drives in Los Angeles; there's just too much traffic" kind of situations.
