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:
Britain and Ireland (72m),
South Africa (58m),
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?
