The part of the article pointing out speed limits alone aren't good enough is important. Lots of people in my city ignore posted limits if they feel they're too low. There can be great side effects with physical changes as well. E.g., narrowing the street can give more space on the sidewalk for pedestrian traffic, or even add a sidewalk where none exists yet.
People will always go the maximum speed at which they feel comfortable. This is true across cultures.
You can't fix this by changing culture; you have to fix it by changing the physical design of the street.
