I don't know, i've probably had more random conversations with strangers either on busses or waiting at bus stops than anywhere else. Especially when the bus is exceedingly late or there's something out of the ordinary happening. People that normally totally ignore eachother will suddenly start talking like they've known eachother for years. There's also been a couple people i've met transit I end up talking to a lot. There's one person, we don't know eachother's names but we know most of the details of eachother's lives.
At a bus stop, yeah, it is kinda strange, cause people are usually there because they have to be, not because they want to. At a hackerspace, at a bar, at a book club, music concert, etc. it isn’t weird all. Some of the best friends I’ve made over the past couple of years (and i mean real friends, the ones you hang out with multiple times a week, go on trips, etc), it almost always was through some kind of spontaneous contact. I guess it depends on where you live. I’ve found (anecdotal evidence incoming) that it is much easier to do so in big cities with a lot of people that are not car-centric.
