The other two thirds of the countries in the world drive on the right including the USA, China and Russia.

Clarification: Vehicles that drive on the LEFT side of the road are RIGHT HAND DRIVE vehicles (steering wheel on right side) and vehicles that drive on the RIGHT side of the road are LEFT HAND DRIVE vehicles (steering wheel on left side).
Why We Drive on that side
The reasons for these distinctions are historical. British horseback riders used to ride on the left hand side of the road, thus keeping their right arm free to offer greetings to passersby or, if needs be, draw their sword. In the USA teamsters used to sit on the left hand horse while driving a wagon and therefore keep their right hand free for whipping the other horses. They decided to start driving on the right so that they could see the passing wheels of other wagons and avoid collisions.
