Yeah, I’m also an American. Those are examples from personal experience.

When I was growing up the dipshit town where my family lived was thinking about installing a roundabout instead of the series of 4 lights in front of the Walmart. The level of genuine panic it caused was insane. Huge groups at city council meetings with signs worried about car insurance rates going up because of “all the accidents it will cause!” Needless to say, it didn’t happen. Meanwhile, roundabouts work just fine for the rest of Earth and I’ve only ever seen one accident in one, due to construction.
