I was waiting for the signal to go green. It was 10 sec to go green, people started honking behind me, asking me to go. I didn't go anyway, many left. You can be good but many around won't let you be.
I feel you.
Also, when the signal is going to turn yellow, I always fear to slow down because of people behind me speeding up to escape red.
And then there are those people who don't check their rear views and those who don't have them at all.
On a positive note, people are getting better. They are making concious effort to make way for ambulances. Some people are now avoiding the right lanes near signals so that people behind can take a right or make an U-turn (I rarely saw this happening until recently and the numbers seem to be increasing).
I believe that Chennai's traffic problem is further worsened by poor traffic management, particularly too many one-ways. These are only creating more of the bottlenecks. At any given junction, there are considerable number of vehicles that would not be there, if not for the one-ways.
