Which side of the road to drive on was decided long before the automobile. In the past, almost everybody traveled on the left side of the road because that was the most sensible option for feudal, violent societies. Since most people are right-handed, swordsmen preferred to keep to the left in order to have their right arm nearer to an opponent. Before automobiles, roads were meant for horse-drawn carriages. The coaches of these carriages have doors on the left side so they were driven on the left side so that alighting and embarking would be safer. During the time when the Horses were used to pull the Carriages the driver had to be situated on the right side of the carriage so that they won't hit their passengers on the rear when they use their whips. This technique was widely used in North America, and people may have started to naturally keep right because this was where the large carriages and wagons were, making riding on the opposite side rather dangerous. As postillion driving spread, more countries may have adopted the habit of keeping right for safety. No matter what side of the road one drives on, in most countries, cars are specifically engineered to drive on a specific side of the road. In countries with right side driving, the driver's seat is on the left, while left hand countries have drivers' seats on the right. In both cases, the seat positions the driver close to the middle of the road for better visibility.
