Anyone ever bought shoes or clothes or tires in the EU? The sizes are absolutely not metric and a complete mess! Not to start about traffic rules, sizes of streets, traffic signs etc. Nothing is regulated, nothing is standardized. But the worst missing regulations which are keeping the continent back are missing standards for train traffic in the EU: E.g. there are about 10 different https://en.wikipedia.org/wiki/List_of_railway_electrification_systems https://en.wikipedia.org/wiki/List_of_railway_electrificatio... in the EU. In addition their are thousands of incompatible regulations regarding train signals. The EU could have high speed trains from Lissabon to Helsinki. But I guess the US will introduce metric units before the EU will solve their train traffic mess.
