Amazing...and kinda unnerving at times.
Just count your lucky stars if there are no traffic circles in your area. I live in an area with a very significant Hispanic demographic, a very significant Middle East demographic and a very significant African demographic. Large parts of the world apparently have never heard of turn signals, and are unclear on the whole green-yellow-red light concept, the “speed limit” concept and the “don’t double park or park on the sidewalk,” concept, the idea that one shouldn’t make a u-turn in the middle of a block, and think that they get extra points from the Virgin of Guadalupe and/or Allah for cutting off other drivers. etc.
We have the same problem in SW Texas (Northern Mexico) at 4 way stops they all wait for someone to make a move and then they all go.
