I agree with you, the issue is that the technocratic powers from those cities I mentioned (I for myself live in Bucharest) will most definitely use the studies made up using this type of data and will apply them as they are, using “the Germans/Swiss/Dutch are doing it so we should, too” as their main reasoning. By the time someone comes in and says that most probably the situations between Bucharest and Amsterdam (to give a random example) are very different it is too late, the measures have already been taken.
