In the BCE (Before the Common Era) days of the Roman Empire, Legionnaires tore throughout the land aboard horse-powered chariots. These had been pushed by charioteers, who generally held the reins of their proper hand whereas wielding a whip to make the horses go sooner of their left.

It’s a typically acknowledged undeniable fact that about 90% of people are right-handed, with a mere 10% being lefties. This oddity of genetics will be attributed to the truth that the mind’s left hemisphere controls the correct aspect of the physique, whereas the correct hemisphere controls the left. 

One concept means that throughout the evolutionary means of making stone tools, which were “invented” more than once throughout history, homo sapiens used their proper palms extra as a result of the cognitive drive that drives tool-making comes from the left half of the mind. Another speculation states that, because of our fundamental want to outlive, we knew on some deeper degree that competitors and cooperation wanted stability to ensure that the species to coexist and flourish. A standard denominator between most divergent teams was that everybody was right-handed, and to advertise the sharing of concepts and assets, everybody stayed that method. Curiously, most primates do not favor one aspect over the opposite as a lot as people.

Given all that, the charioteer holding the whip in his left hand led to chariots passing on the correct aspect to keep away from getting smacked. Therefore, the Romans are credited with inventing the European mannequin of driving on the left aspect of the highway.
