Such thorough and precise inspection, to be honest, I loved to see such issue being discussed on this platform. I don't know where to start with literally Karachi or any other major city of Pakistan except Islamabad (I guess) has severe issues. Consider Lahore fully engulfed in smog, and Karachi - once the city of light - is now just quoted for bad examples. This dumper issue is real and needs genuine care, but alas, no one is serious, the politicians will come and taunt each other. Despite the fact that they all are equal. All this issue demands is: basic governance, following traffic rules, infrastructure and civil sense (and all these/those things you have already mentioned).
