Left or Right? Not Politics, but Driving.
Why do some countries drive on the left, and some drive on the right side of the road?
Here’s one summary, which essentially says that Continental Europe was introduced to right hand driving by a combination of economic factors and the French Revolution. Originally everyone was on the left, because otherwise swords would hit coming the other way (swords were worn on the left because it’s easier to draw them from their scabbards than if worn on the right).
I thought it was interesting. I hope you enjoy reading.
