You have it backwards. There is not one practice that you can just extract and implant into a new culture. They avoid accidents because they have a culture that has grown and valued riding bikes. This culture has manifested in many practices that are taught and reinforced by the culture. The actual individual things are of little significance individually. It is about the awareness and culture pressure to make efforts to always make bikers safer. Just telling people to do this one neat trick will lead to most people ignoring it or forgetting to do it.
Or maybe both perspectives have some truth to them?
Such as:
1) Yes, the Dutch have a great, deeply embedded culture around biking which promotes high levels of safety.
2) But, it is also possible to learn from and integrate a few of the most impactful & compact aspects of that culture to increase safety in other nations.
Without a doubt both have a degree of truth, but we are back to the original problem I was responding to. When you list off those two things it makes it seem like they are both equally true. The thing that deserves the most credit is the culture. The things that are most impactful are partially impactful because of the culture. If you are picking the one change that does not depend on changing the culture for effectiveness, you could very well be getting less than 1/10 of the safety of dutch.
