Poland also doesn't have cultural enrichment barriers. However, the reasoning for not having cultural enrichment barriers where there's a lot of pedestrians is also the same reason why guns aren't popular - there is little violent crime due to the small amount of turd worlders and the crimes committed by the native population are mostly limited to fights, some opportunity thefts, but not violent rapes, stabbings, shootings, terrorism, etc. nearly to the same extent as western europe or the USA.
They had to put these barriers in Germany, France, Sweden - basically every country that accepted large numbers of muslims to prevent spontaneous cultural enrichment via truck/car. Of course, cultural enrichment with a pillar of islam/kebab is still a problem though and can't be stopped with concrete barriers.
