Why is it that different countries drive on different sides of the road?
Answers:
Just convention really.
The Romans drove on the left; as we do in the UK, so everybody else is in the wrong :-) (Kidding)
In order to confuse tourists.
To confuse the people who come over for there holidays!
Its elitist and stupid, I think.
It comes back to the days when you would travel on horseback, - the idea being in the UK that you would be best able to defend yourself with a sword in your right hand against an enemy coming at you from the front. In France the convention was, obviously, on the right, (not too bothered about defending themselves?) - and when the french empire was at its height under Napoleon in the early nineteenth century, all areas under french rule were standardised - hence all of europe drives on the right. Japan drives on the left - presumably because of the same old equestrian reasons in its culture.
To stop the world tipping over.
Apparently there are suggestions top swap the side of the road for cars in parts of the USA, because it is thought the anticlockwise vortices caused by cars passing whilst travelling in opposite directions may gang up to form tornados.
Because most of the rest of Europe and the Americans are all bloody silly!
