The first thing that comes to mind is the whole car break-in thing, where people just leave their doors unlocked to avoid have to replace windows OR people doing that and coming back to people sleeping in the back seat sounds wild to me. Also from what I hear, BART is like Mad FuMax. Yeah sure you'll see some shit occasionally taking any form of MTA transportation, but 90% of the time it's normal. Aside from that, it mostly sounds like every problem we have here, but multiplied.
But again it's just from what I hear, since I've never been there.
