What does this colored world map show?

[AviatorTom]

Here's a map of the world where each country is shown in either Green or Orange.

What do you think each color stands for?

Many people got it.
Green = people drive on the right, most of the world, primarily due to the original German, French and America auto industry
Orange = people drive on the left, mostly former British Empire. Japan because it built its railway with British help.

Driving side.
Europe uses right because of napoleon
England on left so you can draw a sword on a horse
The USA on right because of multi horse stage coaches
In Wales we drive on what's left of the road.

Green: countries that drive primarily on the right side of the road


Orange: countries that drive primarily on the left

Places where the drive on the right (correct) side of the road. Cars are Right hand drive and you pass on the left of oncoming traffic

[AviatorTom]

@Shiprex Which color is that? And what does the other color mean?

[Shiprex]

The coloUr is the orange coloUr and the green coloUr they drive on the other side with left hand drive vehicles ALTHOUGH Sweden historically drove with left hand drive vehicles on the left side of the road then one night (Sept 3rd 1967) they switched overnight to follow the rest of Europe driving left hand drive (and right hand drive) vehicles on the right side of the road

Do the colors relate to population density?
