Is there any social norm I don't know about when interacting with people in public?

The title might be vague because I don't know the right way to phrase this question. I am a student from Bangladesh who came to the UK for studies. Why do people in public just somehow ignore each other? Also is there any problem with be looking around and observing people? When I'm on the bus, I don't like to be on my phone all the time and I want to observe how people look like, what they're doing, who is leaving and exiting the bus. Any feedback and advice on this? I searched about this online but the info I found was unclear
