ABS is definitely mandatory in India. In India we can never tell what is going to happen the next moment.
I have had a heart throbbing experience of hard breaking when a moron on a bike, out of no where, comes from left to the right side of the road and just stops without warning.
The car I was driving was Dzire without ABS and only I know how I controlled the car when it was sliding sideways. That was the day I decided that ABS is not a choice, its mandatory.
Another point is that our roads have so much dust on them, that chances of a vehicle skidding gets higher and higher. And with vehicles getting faster model by model, it calls for more safety that we have now.
@Shynish - I totally agree with you about all the points. Would like to emphasize on Child seats. There is no use if a person wears the seat belt, sits in a car with air bags but holds the child in one's arms. That is actually more dangerous for the kid than the person holding it. Child seats are so much required and helpful. But again, we Indians think everything is investment and should last as long as possible. They think, "A kid will be a kid only for a few years, what to do with the child seat after that?". It is an investment, an investment to safeguard your's child's life. If people start realizing this, that is when they will think of child seats as life savers.
Airbags, you will not need it under normal conditions BUT when it is needed, it is at a time when there is a question of life and death. It is very easy to say that I don't drive on highway so I don't need it. But you will get on highway someday and it is only a matter of a fraction of a second when things can go wrong.
It is not necessay that we are driving recklessly but the guy you hits your car could be.
In developed countries, the roads are of superior quality but the average speed of traffic is usually at or above the limit. Really speaking, the traffic sense is so much better there that it is very easy to anticipate the changes to the road status as we are driving. But if the road conditions are that of slippery like rain, it is really helpful
