2fast4u, you have a point, about using the radio as a medium to instill atleast a basic traffic sense in the driving population. In Chennai, Radio Mirchi does a good job on this front. During their programmes (especially the ones aired during morning/evening peak hours which motorists are most likely to tune to) they keep telling drivers to follow the rules, use low beam in city, drive sanely etc. And I think it helps.
Atleast for me, when Suchitra (hostess of Hello Chennai programme) comes on air and makes a request to "drive with a smile" in that sexy voice of hers, there is no way I could ignore that exhortation.
Another thing that helps is setting an example. We are quick to brand all others on the road as morons, yet almost all of us make one mistake or the other ourselves. Instead of wasting energy on blaming others, if we start practicing the rules, I am sure atleast a few would observe and start following the rules themselves.
At junctions where free left is not allowed, if we stop and wait till we get the green signal, the example we set will be followed by atleast a few fellow motorists. Ofcourse it takes quite a bit of determination to stay put when you have the heavy vehicle behind you revving the accelerator or honking madly to make you move.
