Bangalore-it's a (s)pity

Why do people in bangalore spit so much? Is it because of the paranoia that their oesophagus is always filled with dust and filth and they want to get rid of it by mixing it with the saliva and spitting it out? Is it because they are always disgusted about the traffic condition? Is it because they want to settle the dust on the road by drenching it in saliva? It's difficult to fathom. But it's very very annoying to see someone continuously spitting on the roads, be it an auto-driver or a cab driver or a common man or an industrialist.

When I start for office every morning, I really get irritated to see loads of spit on the roads. It looks like the whole dusty road is marked with dark spots. I really have to look at the roads and walk so that I don't step on somebody's saliva which he/she has indifferently donated to the outside world in an effort to reduce the dust in the air (perhaps). When I was a kid, I was tought in school that people shouldn't spit on roads because it might carry germs of infectious diseases which might transfer through air. I wonder whether people here get the same education in schools as I have seen so many parents walking along the street holding hand of their offsprings and spitting randomly on roads. I might be a little bit sarcastic in this statement, but it is a serious issue. I don't know the solution.

Might be the Government should take possible steps to change the habit of the common people. I have seen inside the software office campus and inside the movie theatres boards with "Do not spit" written on it. May be the same thing could be done in all the places and in hoardings and signboards by the side of the roads (it might degrade the image of the city a little bit to the foreigners, but still better than a foreign citizen experiencing the actual incident). Government can arrange some awareness sessions and enforce some law and fine if somebody spits on the road. Perhaps the Government is too busy in building 9km long flyovers (useless?) and decorating the boulevards. The image of the city and it's citigens is at stake.
