I see kids alone in the subway in Berlin all the time. Berlin is a high-immigrant diverse city with low work and high party ethics. It seems to me that this is more a function of having a somewhat reliable public transport network. When I explored Berlin myself as a kid, all I had to remember was the color of the subway and the stop I had to get off to return home. When I got lost anywhere in the city, all I had to do was find the next subway station, look at the plan and I’d find my way.
