Why do the English drive on the left hand side of the road?
There is a logic that has evolved since “the olden days” about keeping to the left on the road. In “the olden days” people wanted to be ready to protect themselves using their sword whilst they were passing each other on the road. To accomplish this they had to be in the best possible position to use their sword in order to protect themselves. Since most people are right handed, they felt it convenient to keep to the left so as to be able to use the sword in their right hand. History recoreds that keeping to the left came into force as early as 1300 AD, when Pope Benefice told all his pilgrims to keep to the left hand side of the road.
