Here you can see that the person driving the car has to turn right, but he is not bothered that he must have taken the extreme right lane before nearing the traffic lights.
Above act may seem to be small, but such road manner may result in Road accident or Road rage incident. If something goes wrong, it could be fatal, to any extent.
YOU must not move outside in such a way which may result in any untoward incident. Be a safe rider, always. It is better to be disciplined mover, rather to repent later.
