why is there left hand driven cars in some country and right hand driven cars in others and how is the choice?

Answer 1

It's simply a matter of tradition. In some countries, horses and carriages travelled on the right side of the road, in others, on the left.
Interestingly enough, in the 'Down Under' countries of Australia and New Zealand, where the water goes down the drain counter-clockwise and they drive on the left side of the road, they also walk on the left side of the sidewalk, bike on the left side of the road and swim on the left side of the pool lanes. It isn't just the driving that is affected, but every mode of travel.

Answer 2

Originally it had something to do with whether countries had castles or not. Spiral staircases are always designed so that the defending warriors have more sword room. England had the most castles when cars started being produced and everyone in England is right handed so when they invented cars they put drivers and their country on the right side of their cars and the road.
American Henry Ford was a lefty, so he put drivers (and America) on the left.
Since no other country produced cars of their own until in the 1960's, for them, it depended on from whom they imported most of their first cars.
