Why in American cars steering in left sidebut in India it is in right side?

Answer 1

You want the steering wheel closest to oncoming vehicles, so you can judge distance better. In the U.S. we drive on the right side of the road and in India they are supposed to drive on the left side. But in India the reality is they drive on the left or right of the road? Basically you start on the left of the road, unless it is occupied. In that case, go to the right, unless that is also occupied. Then proceed by occupying the next available gap, as in Chess.
About a quarter of the world drives on the left, and the countries that do are mostly old British colonies. This strange quirk perplexes the rest of the world; but there is a perfectly good reason.
In the past, almost everybody traveled on the left side of the road because that was the most sensible option for feudal, violent societies. Since most people are right-handed, swordsmen preferred to keep to the left in order to have their right arm nearer to an opponent and their scabbard further from him. Moreover, it reduced the chance of the scabbard (worn on the left) hitting other people.
Furthermore, a right-handed person finds it easier to mount a horse from the left side of the horse, and it would be very difficult to do otherwise if wearing a sword (which would be worn on the left). It is safer to mount and dismount toward the side of the road, rather than in the middle of traffic, so if one mounts on the left, then the horse should be ridden on the left side of the road.
