Interesting that a lot of US road signs have words on them: https://ygraph.com/graphs/roadsigns-20120316T030941-ekrruua.... , or are obvious, whereas in Europe drivers need to learn what they mean: https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh...
For example the yield triangle, no stopping and no parking are probably unfamiliar to US drivers.
Meanwhile all Alfa Romeo Quadrofoglio drivers might be mistaken for drivers with missing limbs in Japan.
