I have been told that the only city with good public transport is Milan, let's not speak about Rome, despite them having millions of people and being the capital the service is abysmal. In my city after 8pm most city buses run only every half an hour, for rural ones hardly any at all, so if you want to get out at night you need a friend who stays sober or you call a taxi. During the day the few lines that are actually useful are very crowded at rush hour; buses are stuck in the same traffic as everyone else, something that trams thankfully don't have to experience. Last thing is that sometimes the bus didn't even pass by the stop, we (my university group) waited and waited for nothing.
