The fact that some countries in Europe hold people responsible for their own actions was one of the very first things I noticed when I travelled there. The curbs are not painted yellow, there are no "watch your sep" or Wet Floor" signs, in fact, some of the canals in Amsterdam don;t really even have a curb on the edge. There is no warning at all. You are expected to be able to pay attention to what you are doing, where you are going, and if not-too bad. Loved that.
