There is no area that one cannot walk around by oneself at 3 a.m. It is safe and it also feels safe. No muggings, no drive by shootings, no beggars, no filthy slums, no barbed wire protecting property, no police sirens in the background. Instead small, one to two man, police stations can be found on each square mile. During day time police patrol the streets with old fashion bikes.
People are patient and well behaved.
There is no jay walking. Even at night people stop if the pedestrian light is red independent if there are cars around or not. They strike me as more law obeying and rule following than Westerners. The streets are tidy. Everyone is well dressed, mostly in conservative colors such as bland shades of grey and black.
