In bangalore many times only driver is there doing conductor job also?

in bangalore many times only driver is there doing conductor job also. this is extremely dangerous as he cant concentrate on the traffic. this is worse than using mobile while driving. while i appreciate the driver for safe driving, he will be too slow, causing financial loss in terms of time and diesel (inefficient if the speed is less than 85% for diesel engines) it will consume 30% more diesel. why not employ sufficient conductors? while unemployment is hovering?
