I'll leave the article as-is. This isn't the first article to grace HN that stated that Japanese companies tend to be slow adopters. What I want to know is why the highlight on human traffic signalers as an indicator of how "backwards" the culture is technologically.
It seems to me that if the goal is not just public safety, but to put a human face on law enforcement, a human traffic signal is exactly what is required. True, a robot can do the job, but a robot would be ineffective at the task of humanizing the reasons behind the laws and in providing assistance to people who need it.
