People should not use mobile phone while driving or riding. I have noticed people using mobile phone while driving or riding which is not only risky for them but also dangerous for other vehicles. They are fully engrossed in their phone and don't realise that they are changing lanes or driving/riding too slow, which is even without their knowledge. They think they are driving correctly however it becomes dangerous for people following them. They cause traffic jams or even lead to accidents. The bikers have the phone held with their cheeks and shoulder and have no attention on the road or traffic. The Ones driving cars or auto rickshaw have one hand on the steering or handle the other holding the mobile phone. I feel this is too dangerous and This should stop.
