That was because yours in a pleasure trip, once we were coming back from Jaipur to Delhi the driver took a different rout as the highway was jammed by Gurjer agitation. The rout, almost 200km long was through the jungle or unlit dark rough under developed roads. Later, after a couple of hours' journey we came to know that some of the buses were burnt down ahead and we were stopped on the way. We started in the morning when the news came that there is all clear and safe to travel So the journey that takes about 6 hours in normal course took us 18 hours. That was one of the worst although I have gone through many such rough trips. Some of them were not so bad but not pleasant either.
Smething similar happened to us once when we decided to drive all the way to Bombay from Mangalore .We had problem with the cars clutch plate and had to stop at Goa where we could find no accommodation, that being the peak season..We took turns and slept in the car since all five of us were there...It was some experience, but the children loved it :P ,they still talk about it !!
