I don't see why a country should accept any lowest common denominator of regulation for local taxis. Something that literally only affects the area in that country. If I need to get from the Berlin Aiport to the city centre then it doesn't matter what kind of cab service NY or SF has. They only cabs available there are going to be cabs and rides the Berlin or German government allows to operate.
