Hm, this is what I found:
In 1998, archaeologists found a well-preserved track leading to a Roman quarry near Swindon, England. The grooves in the road on the left side (viewed facing down the track away from the quarry) were much deeper than those on the right side. These grooves suggest that the Romans drove on the left, at least in this particular location, since carts would exit the quarry heavily loaded, and enter it empty.
Some historians, such as C. Northcote Parkinson, believed that ancient travellers on horseback generally rode on the left side of the road. As more people are right-handed, a horseman would thus be able to hold the reins with his left hand and keep his right hand free—to offer in friendship to passing riders or to defend himself with a sword, if necessary.
The first legal reference in Britain to an order for traffic to remain on the left was in 1756 with regard to London Bridge. The Highway Act 1773 contained a recommendation that horse traffic should remain on the left and this is enshrined in the Highway Act 1835.
In the late 18th century, the shift from left to right that took place in countries such as the United States was based on teamsters' use of large freight wagons pulled by several pairs of horses. The wagons had no driver's seat, so a postilion sat on the left rear horse and held his whip in his right hand. Seated on the left, the driver preferred that other wagons pass him on the left so that he could be sure to keep clear of the wheels of oncoming wagons. He did that by driving on the right side of the road.
There is a popular story that Napoleon changed the rule of the road in the European countries he conquered from keep-left to keep-right. Some justifications are symbolic, such as that Napoleon himself was left- (or right-) handed, or that Britain, Napoleon's enemy, kept left. Alternatively, troops passing on the left may have been tempted to raise their right fists against each other. Forcing them to pass on the right reduced conflict. Hence, island nations such as Britain and Japan (using ships to move troops around and having less need to move them overland) continued to drive on the left. These stories have never been shown to have a factual basis and appear to be legends.
Countries that became part of the British Empire adopted the British keep-left rule, although some have since changed. In Canada, the Maritime provinces and British Columbia initially drove on the left, but changed to the right to make border crossings to and from other provinces easier. Nova Scotia switched to driving on the right on 15 April 1923.
Le coeur a ses raisons que la raison ne connaît point. 
never made sense to me, majority of people are right handed, logically youd want the right hand on the wheel at all times!
really?? i would think its easier to steer than it is to shift precisely, i sometimes even steer with my knees (kids, don't try this at home) also, the same with accel/decel, i think it takes a bit more precision to both these actions, while the clutch is sometimes not even used. There's a nice resting spot for the lazy left foot on auto trans. Also, turning the ignition with the left
So you'd prefer to change gears correctly over control of the car!? Ok...
And if you think keep right traffic is the correct way think again, it all began in the French revolution where the people chose to change anything to do with the monarchy including the side of the road they would drive their horse and carts. Then thanks to napoleons expansions spread this throughout Europe. Ofcourse the USA chose the same path in their revolution, distancing themselves from Britain, and duckling up to their French ally!
