I have family that live in SF proper. I remember talking with them about the demeanor of BART's riders a few years back. They had mentioned that they had to move cars earlier that day because someone was smoking a very large joint and it was fouling the air in their car quite badly. They concluded the anecdote with something along the lines of " you know, it's just like every other metro system, nothing you can really do". I was like, no way. No other metro system is like that. I literally know of no other metro system where people are smoking in the cars, let alone pot, let alone to the point where the air is foul, let alone that you just think that's a normal thing, let alone that they aren't thrown off the car by law enforcement, let alone by the other passengers. My family members thought I was joking, that this kind of thing must happen all the time in nearly every other metro system, at least a once a day occurrence. The disconnect was just flabbergasting to me.
