I once saw this movie where several UK English words were compared to US English and US came of very “simplified”. Ie, pavement “Side walk” (because walk on the side). And several things like Lorry and Hauler all becoming “truck”. I guess it was very cherry picked (I can’t find it now sadly).

Ah well, I once read an argument for “EU English”. If it’s anything like my Dunglish (Dutch-English “What talk you about”) it would indeed be simplified.
