Genius instead of asking questions that do not make sense do some reading on the subject Indian highways constitute approximately 2% of the total road network of India for a nation of 1.2 billion with almost 50 percent traffic, that speaks volumes.
And instead of asking me you could easily google and get your answers ..LOL....
Dude,I need not rely on some exterior sources for this.This is a very big country
and you can't construct highways each and everywhere as you wish.
Now I am forced to ask you one simple question.Edited
Again just show me where India does not have a highway?
