Yes those are some rare exceptions but most of them will behave in the way they are supposed to be and if not they will get into deep trouble. I have been to other countries and where they drive car by following all the rules and even Indian driving license got some power in other countries, where getting a driving license while we have valid Indian one will be easy.
India progressed a lot compared to where we were in the last 20 years that is true, but we fulfilled our potential to grow then we haven't yet.
India sure does have a lot of room to grow and what you say is true that it has developed a lot over the last few years.
On the other hand, Indian people's civic sense hasn't seen much growth yet.
People have been doing the same mannerless things that they have been doing over the years.
That is something that needs a rapid change if we have to progress competing with other countries.
