Driving on the left

Driving on the left-hand side of the road isn't as uncommon as people might think.
Roughly a third of the world's population drives on the left.

Countries that drive on the left are:

India (1366m),
Indonesia (270m),
Pakistan (216m),
Bangladesh (163m),
Japan (126m),
Britain and Ireland (72m),
Thailand (69m),
South Africa (58m),
Kenya (52m),
Australia (25m),
Sri Lanka (21m),
New Zealand (5m)


Trains, well, that's a different story.

And which side should you stand on an escalator if you don't want to be tutted at?
