>Way my colleagues told me, circulation is such a mess there’s no way you can check all around you
It's not so much that you can't, but that most people don't and with no driver education and no enforcement of traffic rules, you are stuck in a shitty nash equilibrium. I learnt driving in Canada, and I have tried to continue the same driving habits in India - because that is the only way I feel safe while driving. I simply can not change lanes without checking the rear-view mirrors and a shoulder-check because I am utterly terrified of what could happen if I don't.
At the same time, I am also completely aware about how 99.9% of drivers on the road are operating. So, I have to be cautious that any car could try to nose their way into the road in front of me even when I have right-of-way because that's just how things work here. It is stressful and horrible.
