It always looks weird to see a movie or TV show made in Britain where they drive on left-side of the road. You would think after all these years someone would have done a study and determined which is actually better- right-hand drive vs left-hand drive given the confusion, extra-cost and even safety risks of having to switch back and forth as you travel about the world. It would be interesting to know which is most common world-wide. To me right side makes more sense since you can better judge the position of an oncoming car if you see it from the center of the road. And the fact that you use your right hand for shifting gears (in a straight-drive) favors "right"-side drive- unless- ofcourse, you are left-handed! . . . . .
