Well, what do you expect? They drive on the wrong side of the street. 
Another tangent. Do you know why England drives on the left? It is due to sword fights.
You see, if you are fighting with swords, it is best to march past an opposing army on the left side. This is because you draw with your right hand from your left side in the direction of your right side. So, if you are marching on the left and need to fight a passing army on the right, you can draw your sword and slash your enemy in one continuous motion. So, when everyone fought with swords, people always passed on the left.
Then rifles became commonplace.
You see, if you are fighting with a rifle over our right shoulder and needed to attack on the fly, you would drop the rifle stock into your left hand, put your right hand around the trigger and pull the butt up to your right shoulder. Doing this in a fluid motion would have you aiming to your left at first. So, Napoleon eventually realized that switching the side an army marched on would give him a tactical advantage, and eventually every army followed suit, except England. England, being sea locked, never had a large army and relied on its navy for protection, so there was no point in adopting it. Then cars were invented.
I also just found out why men stopped wearing dresses (everyone wore dresses at first) and started wearing pants. That's quite interesting too, with war and religion mixed in.
