Why do we drive on different sides of the road globally?

We drive on different sides of the road around the world because people made rules that fit how they lived and moved together.

Imagine you're playing a game with your friends in the park. If everyone decides to walk on the left side of the path, it’s easier for everyone to pass each other without bumping into one another. That's kind of like what happened when some countries chose to drive on the left side, it felt natural and worked well.

Now imagine your friend group moves to a new city, and they all decide to walk on the right side instead. That’s how some countries ended up driving on the right, their rules changed because of where they lived or who they were learning from.

It's like when you switch hands for writing, it might feel strange at first, but soon you get used to it. Some places kept their old rule, and others chose a new one, just like how you and your friends can have different ways of playing the same game.
