Eh I don't think so. Commutes are as clean and peaceful as they can be in the Netherlands or Switzerland and people are no less buried in their phones with noise-cancelling earbuds on.
The Netherlands even has segregated busses for asylum seekers because there was too much violence. Dutch people have their own busses and asylum seekers are required to use a separate bus with extra security. Upside is that asylum seekers don’t have to pay for a ticket.
Ofc there's a non-zero number of crazies, violent people, sexual harassers, etc. That's a certainty in a system with 400 million trips a year! But then please don't leave your home, there can be an ax murderer lying in wait at any corner!
It's a tale as old as time.
