Lost in all the commentary of 'in Europe they do THIS, and in the US we do THAT" there is one thing missing: Just because a VW Golf can do "this" in Europe does NOT mean that it can do the same thing west of the Atlantic- THEY ARE NOT
the same car!!!!
They have different suspensions and different bumpers and some chassis differences, too!
Even between Canada and the US there are substantial differences. As an example, every car that comes out of Japan to N America is put on the boat as US Spec. However, to be allowed entry into Canada, it requires different bumpers which are installed at port of entry. Doors are different, as a seatbelts. Canada has a 5 mph bumper standard the US has 2.5. Canada requires much heavier "anti-intrusion" door safety beams than the US does. Lighting
standards are different. Seatbelt stress tests are more stringent in Canada and the belt attachment points are much heavier in Canada.
European cars generally have far stiffer suspensions. Cars built to euro-spec are not popular in the US - they ride too stiff and harsh (not "pillowy" enough)
Various makers have spent huge amounts of cash to make cars "saleable" in the US by changing to softer suspensions, putting in lighter bumpers and lighter shocks, all of which impacts greatly on how well a euro-spec car would tow something vs how well its US counterpart could do it.
The cars from many makers sold on this side of the pond would be a US spec version that would be illegal for sale
in the Euro zone (and often in Canada they would also be denied entry)
Of course the euro spec one can do things differently - its a different car! - looks the same, but it is NOT the same car!
