No matter how many times you go to a country like England or Japan, it s still a little shock to get off a plane and see people driving on the left side of the road. That is, if you re from the roughly 75 percent of countries that drive on the right side of the road. Wrong in this case is relative, depending on where you re from. There are a lot of differences in how individual countries do things, of course. The metric system might be the biggestвthe United States is largely on its own in measuring with feet and inches. Currencies and exchange rates are certainly country-specific as well, not to mention languages and customs. But all of those things go back hundreds of years. Automobiles arrived in the 20th century. Why couldn t the world standardize one system for driving? It s harder than you might think. Despite the modern invention of the car, the side of the road on which we drive has a centuries-old history. The fact that most people are right-handed is the biggest factor contributing to which side of the road people initially chose. Ancient Romans drove chariots with the reins in their dominant right hands to allow them to whip a horse with their left. That way there was little risk of accidentally whipping a passing chariot. But if a warrior needed to do battle from a horse, he could attack a passing opponent on the right with his stronger hand. For centuries, driving on a certain side of the road was mostly just a custom.
There weren t that many travelers and roads weren t paved or marked to direct traffic, so it didn t matter too much. But as more people started driving, some uniformity was needed. One of the biggest influencers of driving direction was Henry Ford, who designed his Model T with the driver on the left. That decision meant cars would have to drive on the road s right, so that passengers in both the front and back seat could exit the car onto the curb. Many countries eventually followed. Canada, Italy, and Spain changed to right-side driving in the 1920s. Most of Eastern Europe changed in the 30s. Scandinavia waited until the 1960s, but its countries eventually changed to the right, too. Things got interesting in colonial countries, especially in Africa. France had long been a right-side country and Britain a left-side country, so their colonies usually followed suit. But when they became independent, many sought to normalize with their neighbors to make things easier. Today, most African countries drive on the right.

So why do close to 50 countries still drive on the left? The short answer might be stubbornness, whichвwe should be fair hereвis part of the same reason the U. S. still sticks to measuring in inches and feet. But the more nuanced reason is momentum. Cities like London were designed to accommodate left handed driving, so switching would be no simple tweak.
Changing the rules of the road is a very complex and expensive thing to do. And the more time that goes by, more cars on the road makes it even harder. Itвs certainly not a debilitating difference to foreign drivers. After a few minutes, your mind tends to adapt. But the most fascinating places to see the confusion might be at border crossings, where drivers are required to immediately change sides. British drivers who take their cars under the English Channel need to swap when they arrive in France. The same is true when crossing borders between China and Pakistan, as well as China and Hong Kong. Where possible, that seems likeВ a good enough reason to cross a border on foot. Why do some countries drive on the right side of the road and others on the left? Back in the times of highwaymen, it was seen as bad manners to pass an approaching traveller on their \’\’weaker\’\’ left side – the sword, pistol or fist usually being better wielded in defence with the \’\’stronger\’\’ right arm. So, to appear trustworthy gentlemen, travellers should pass on the right of each other and hence move along the left side of the road (or muddy track). This custom stuck and lead to the way we, and many countries over which we have had influence, drive today. Orginally armies (in Europe at least) rode their horses and marched on the left-hand-side of the road.
This left the sword hand (right for the majority of the population) in the middle of the road – allowing for easy combat. Napolean, as a mark of defiance, order his armies to march on the right hand side of the road. Thus in any country that was conqured by napolean (or later collonised by those countries) people rode and later drove on the right hand side of the road. I understand that in the US driving on the right was originally a mark of defiance to the British. Napolean taught his army to use their swords backhand during a duel to allow them to attack on the right side. Driving on the right evolved from this in the countries he invaded throughout Europe. I suspect America drives on the right to be contrary. Because it\’s faster than walking. Is misspelling \’Napoleon\’ a mark of defiance against the emperor? Imagine you are going to mount your bicycle or motorbike. most people swing their right leg over the saddle. In Britain,India, Japan etc, you are then facing left, ready to move away from the kerb. In Europe, US etc, you either have to mount with the left leg first, or step into the road to mount with the right leg. It\’s about the only advantage there is of driving on the left. The general rule is that former British colonies drive on the left, everybody else drives on the right. Exceptions are Canada and Ghana, which drive on the right, and Japan and Indonesia, which drive on the left.
