Before this morning, if you'd asked me for one fact about Samoa I would have told you that it's a country that's pretty handy at rugby.

But if you'd asked me to follow that up with a second piece of info I would have been struggling.

Not any more. Samoa has just become the answer to an automotive trivia question, as country that switched from driving on the right to driving on the left.

The logic behind the decision is simple: many Samoans expats live in Australia and New Zealand, both right-hand drive markets, so switching sides will make it easier for them to import secondhand cars.

Many locals - especially those with left-hand drive cars - are less keen. They've even set up a protest group called PASS - People Against Switching Sides.
