I personally that the 65 KM is alright for all of us. Not everyone is a perfect driver and there are many teenagers, ladies, babas and other nasty drivers like staff car ones who don't care to follow any discipline when the bosses are not around.
If speed is to be folowed then we have to train all of our drivers regarding rules and regulations etc of the traffic.
Lesser the speed the lesser the chances of accidents and almost nill the chances of severe accidents.
