Assuming you’re the first to explicitly point out that lemon market type of feature of ‘random social interaction’, kudos, I think it’s a great way to express certain extremely common dynamics.
Anecdote from my country, where people ride trains all the time, fitting your description, although it takes a weird kind of extra ‘excuse’ in this case all the time: It would often feel weird to randomly talk to your seat neighbor, but ANY slightest excuse (sudden bump in the ride; info speaker malfunction; grumpy ticket collector; one weird word from a random person in the wagon, … any smallest thing) will an extremely frequently make the silent start conversation, and then easily for hours if the ride lasts that long. And I think some sort of social lemon market dynamics may help explain it indeed.
