Especially late at night, but it works during the day too. I think because you’re not on the move but you’re also not at a destination or at home. It’s kind of like the ultimate in-between state. There’s something very romantic about it to me, and I like other “in-between” settings for the same reason, like airports and rest stops. I think it’s because your thoughts appear more naked to you when you don’t have something familiar around you to latch on to. And you also aren’t in a position to take any kind of action at the present moment, so it’s easier to confront your thoughts. There’s a book called Non-Places: An Introduction to Super-Modernity by Marc Augé that kinda speaks on this. So I’ll recommend that too.
