Found this interesting Wikipedia article about driving on the left or right side of the road. According to Wikipedia...
"About 34% of the world by population drive on the left, and 66% on the right. By roadway distances, about 28% drive on the left, and 72% on the right, even though originally most traffic drove on the left worldwide."I was fairly sure we were in the minority in Australia, driving on the left. I knew they also drove on the left in the UK, New Zealand and South Africa, but I assumed that pretty much everywhere else in the world drove on the right.
Turns out that there are many other parts of the world who drive on the left, including Japan, India, Hong Kong, parts of south east Asia, parts of south eastern Africa, and some Pacific countries. I also learned that some countries have switched their side of the road over time. Interesting.
Go here to see a list of countries who drive on the left, and here to see a list of countries who drive on the right.
