Mr. Dharam Singh's priority is not to rename Bangalore but to make it better than what it is. Renaming does nothing to the man on the street other than making his/her life more miserable (changes in University, hospital, sign board names etc). Let Mr. Singh find a way to just improve the traffic flow in the city and see if the people are happier.
Once again, you got the wrong item in you To-Do list Sir and I sure hope you read this.
