Those who live outside of the US, what's something Americans aren't ready to hear?

Ok another thing people haven't really touched on is government restrictions on dangerous shit generally. I'm not just talking about guns, but also cars. When I was in the states I saw so many car accidents and bits of car on the road. That doesn't need to happen. It turns out that if you have proper driving tests and mandatory classes, people don't crash as much. Same with guns though. Owning a gun is fine if you learn how to properly use and store it.
